What test technology involves the common sense of the domain to already made common sense in manufacturing industry. In the implementation that in automation of new material development, production process, special type production technology, intelligence turns system and product of Electromechanical an organic whole, in all sorts of functions when equipment enlists in army come true and be being developed, test technology had mainer and mainer effect; The virtual reality that checking a domain uses a field, vision of such as computer, mechanical, touch, use the electronic device such as feeling (wait like garment of glove of head tracker, data, data) successful development, and the development of the technology of new test system that is a delegate with fictitious instrument and VXI technology, make check a technology to make the independent field that has feature of much discipline across, computer technology makes check a system to be changed to software from hardware send fictitious production technology (VM) as a kind of new production strategy, the fictitious design that involves a product, fictitious treatment, fictitious assemble and function is fictitious detect wait for each respect. Inside the research limits of respective independence, afore-mentioned respects gained certain headway. How to draw lessons from the development experience of traditional manufacturing industry, union checks computer application gain of the technology, make fictitious production technology the confluence with each better level, conduce to the development of the product and production, it is the problem that is worth exploration. The necessity that system of 1, fictitious test builds is fictitious production technology, say to draft real production skill again, it is to be below the premise that the computer develops at full speed, from fictitious exterior design, motion emulates what wait for a respect to take the lead in breaking through and put forward to create the strategy. Because design, make and assemble the influencing factor that waits for domain existence to differ, each domain development is accordingly lopsided. Generally speaking, fictitious production technology builds sound fictitious production system above all, choose reasonable fictitious production target, what fall in the light of all sorts of fictitious production environments is fictitious make and fictitious use information, undertake all sorts of emulation, include visible engineering analysis; To a large number of tests that be made actually and exist in function test information undertakes an analysis, revise fictitious design and fictitious make concerned parameter, it is good to get workmanship sex reach accord with use want virtual reality (VR) the new-style and alternant interface of the subjective and overall investment that waits for traditional interactive interface to recruit a person from popular graphical operation interface, outstanding three-dimensional game, fictitious instrument (VI) the development that makes instrument hardware is changed to software, make people realises: What place of fictitious production technology has is macroscopical the feature with microcosmic virtual reality, make its development should assist next abiding by in the computer actual design, make, the law that assemble and uses, build fictitious test system in fictitious production technology namely (VT) . The use that a when fictitious production technology develops objective reason is a product total lag at making, and make lag at the design, and the subjective sex that designs go-between is existing with all sorts of external condition in make and be being used not the place of photograph be identical. Be like: Products plan includes hardware data to choose, design of spare parts structure, spare parts is machined and assemble wait for a respect, need those who consider part of the mechanical function of material, product to move, the element such as statics function, hot property, report function; The function of product or spare parts is by each the test process of level identifies basic parameter information, seasonable feedback, control will assure. Enter fictitious production field, must be in fictitious fictitious test identifies in the fictitious test that makes each level basic parameter information (this kind of fictitious test is basic parameter information must be had fall in computer environment, fictitious produce the feature with each current level) , the development that such ability make fictitious production technology is a product truly, production and use service. In designing a process especially, consider the matter of the respect such as technical, economy, for instance the development of new product used new material, new structure to wait, a lot of variable, make products plan from just beginning can be optimized relatively only. Accordingly, build fictitious test system from bottom, make material, spare parts, product is below fictitious production environment, have those who accord with operating condition, perforative and fictitious design, fictitious treatment, fictitious assemble the fictitious test information with fictitious performance characteristics more be necessary. Real manufacturing industry, imitate signal is basic test message, imitate signal enters signal processing system through sensor in, get concerned data, use at analysis and control. In fictitious production technology, those who use is digital signal, because this is tectonic,all sorts of data sensor and data set become a software, in the graphical interface that changes in the window, sensor of data of have the aid of and data set become a software to construct conveniently fictitious test system, in fictitious test the environment falls " online " or " from the line " test fictitious product and part, it is necessary. Still can know from the analysis above, fictitious test system unlike real test system, real test system is changed in A/D and D/A there are a large number of jobs to want to do on the respect, with a view to of fictitious test system builds a model. 2, the research content of fictitious test system is visible the 2 dimension graph that makes the many symbol in fictitious production technology and number are changed into easier understanding and model of three-dimensional and hypostatic image. To data analysis character, the progress of virtual reality, the data that provided 4 safeguard for people is archetypal, this data prototype has the property such as grain, weight, color, sound, in the emulation work environment that has interact, the person can be faced directly in data prototype, system of tectonic and fictitious test, feel through data sensor, measure, product of understanding, analysis and spare parts are in the change in fictitious test environment, undertake the historical backdate of one dimension time and foreground are looked into, make person by lag, passive participator becomes banner, active participator. Spring back motion is the fictitious sphere freedom that develops successfully with exemple, sphere has a variety of appearance, dimension, weight, grain, property such as color. Accordingly, in fictitious test system, besides can describe process of campaign of free spring back realistically, still can be opposite the stress of the sphere in motion, be out of shape, the change of appearance, dimension makes a test. Be in fictitious in making, the form of fictitious spare parts surface roughness of precision, dimension precision, surface, stress distributings and the vibration of fictitious product, be out of shape and all sorts of invalidation property that can use data prototype try to emulate reach visible, namely fictitious test. Plan institute is shown on for sketch map of fictitious test environment. The research content of fictitious test system includes: The fundamental of fictitious test system and method, the method building a model of information of object of fictitious test system, fictitious test, fictitious test, a few main fields such as the description of fictitious test environment and law of unripe set prescription. The working platform that the window in showing level computer technology changes, three-dimensional hypostatic description, icon turns an operation key and modular can inspect an analysis software and finite yuan of technology, had been fictitious test system build the base with was established certain. Build fictitious test system to should consider the following issues: Above all, should use technology of new generation artificial intelligence, derive tradition number emulates the part that analyses methodological maturity, use object-oriented analytic method and the fictitious test system in building fictitious production course, this kind builds the organic component that should make fictitious production system, can regard the feedback of fictitious production system as controller then. Look from theory and realistic point of view, such system already can be built. Because will look from production process,this is, the impact between object of treatment system, treatment and treatment process is relatively clear, random element easily fictitious, nonlinear systematic processing technique is more mature also; In the meantime, the operating system that the development of computational technology changes to the window from authoritative mode of operation, was the building of fictitious test system in fictitious production process to offer etc from the online operation that asks very tall solid fortune calculates fictitious process foundation and draw lessons from. Of course, new generation artificial intelligence is checking theory of technology, control and computational method to go up should more shirt-sleeve and much information, it is better to offer coordinate and interact. The 2nd, the subsystem coupling that place of law of fictitious test systems analysis involves, disperse changes the method building a model of analysis and system to should have visible feature. Because the system in fictitious production process is kinetic function (include to input type and systematic model type to wait) relatively affirmatory, should gift only parameter with relevant, not quite much property can. Be like: The difficulty that these attribute have different and fictitious test coefficient (existing much experimentation model and experimental data already can provide enough basic information) , the module of fictitious test system that pressed a category to build low precision, common precision, high accuracy and economical accuracy from the level with practical project to whole and fictitious production system so, reduce the difficulty that maths handles, the application of group of facilitating project technology. Anyhow, the fictitious test system in specific and fictitious production process, its should have: Consistency - - namely the complexity of fictitious test system is reduced on visible interface, metabolic pattern is more definite, variable is handled easily. Versatility - - a complex fictitious test system can be used basic " yuan " software package will combine, through gifting the attribute of different level is worth, can get indication intuitionisticly as a result. Expansibility - - as the amplification with inevitable system, open module interface encode offerred possibility for object-oriented process designing. 3, the working method of fictitious test system and look into at present, what need to solve above all is fictitious design, fictitious treatment, fictitious assemble and fictitious in using, check the standardization of information. For example in conventional test technology, the signal such as force, sound, smooth, report is basic test message, in fictitious production technology, all sorts of attribute are basic test information, must be in fictitious make each phase unite a consideration. The expression of fictitious test information is virtual reality be able to one of practical keys. It is with color exemple, person eye can identify gray scale of more than 20 class only commonly, be opposite namely gray scale is not sensitive, but person eye can identify the color that amounts to thousands of kinds of different chroma and brightness. Accordingly, the great information content of color attribute is used successfully already at flow of metallographic ration analysis, plastic fuse-element to analyse imitate, wear process; The impact that if car ABS device is in fictitious test system,has again experiments, be with finite yuan the analysis is a foundation, convey jointly by color, grain and weight. In fictitious test job, should establish target of modular ideal and fictitious test above all, pass reasonable maths derivation or test information data prototype by what beg a project to build mathematical model to regard fictitious test as the object instead from inside economic data, fall in visible environment next, build the fictitious test system such as static state, trends and hot condition. In fictitious test system, OK even the entity of small quantitative change that the change of fictitious treatment and coefficient of expansion of fictitious use central line creates imitate, sensor of data of have the aid of and data set become a software to construct conveniently fictitious test system, in fictitious test the environment falls " online " or " from the line " the movement condition parameter that tests fictitious product or part, use the computer powerful computational function analysis is fictitious the influence that is out of shape the product assembles quality and character of service. is the interference that considers appearance, measure only not just. Ground of data sensor part draws lessons from imitate to measure sensor the action in experimental system, rise to communicate the action of variable information in fictitious test process. From specific fictitious test the procedure looks, want to consider temperature, active force, weight, length, speed and acceleration to wait for data variable already, the variable application in wanting to consider system of specific and fictitious test again, whether to activation namely certain parameter. Press data input-output means and processing technique classification, data sensor also can be pulse type, continuous with frequency change type. Those who need an attention is much (data) the follow-up processing respect that the information confluence of sensor spends a problem to study in elephantine robot the process is medium has included concerned research, the content of this respect will be made additionally discuss. 4, conclusion is fictitious test a system build, can make classics of product all previous fictitious design, fictitious make, fictitious assemble and fictitious use process, gotten fictitious test information can be used at improving parameter of improvement fictitious production technology; As a result of built fictitious test the system is in the extensive sex in fictitious production technology, can make system of whole and fictitious production technology more complete, more practical change. Accordingly, build fictitious test system, have far-reaching sense, and the development of computer technology and the many and economic data that already gathered make of fictitious test system build the possibility that had reality.
