【正文】 le domain in the manufacturing domain ( production planning is laid down , processes , assembles and is tested ) from the tradition of the domain of technique of simulation application from the course developed . In a word, the application for puter simulation has provided the new stage to the development of advanced manufacture technique , and has also put forward the higher requirement , and the application of technique of simulation at present possesses following characteristic and trend : The application in whole product life period of 1 puter in table simulation 1） The unprecedented enlargement of the application scope of technique of simulation. By studying the dynamics property the to make the object (product), kinematics property, process and assembly course of research product, enlarging to studying design and the operating making the system , the advance side by side onestep enlarges to the rear service supply , inventory control , organization of product development course and product test etc at the aspect of the object and the purpose of simulation , involves making each aspect of enterprise 2） Combine distribution of simulation that brings with the work technology. Distribution of simulation is by the distribution decision of manufacturing. The generally thought itself such as quick manufacturing and invented enterprise etc has the person who cooperates a meaning in work implementation place far away from home basseted on 4 3） Each other bine with diagram and the sensor technology, and makes the interactivity of simulation strengthen greatly . Having formed draws up the solid manufacturing (VM: from this Virtual Manufacturing ) and the invented product development ( VPD: Virtual Product Development ) and the invented test ( VT: Virtual Test ) wait the new generally thought 4） The Integra ionization of technique of simulation application. Namely the synthetically application technique of simulation, product development and the manufacturing environment that the formation can move The object of technique of simulation application is seen, and can be divided into 4 kinds with simulation applied in the manufacturing industry: Towards the simulation of product Towards the simulation with equipment of manufacture technology Towards the simulation of production control Towards the simulation of other link of enterprise. Will follow above four aspects in third part of this text, and introduce the concrete application in the manufacturing industry of puter simulation. What the virtual reality solidly with draws up was made generally reads except this , sum aggregate onetenthizations trend that the concentration has embodied the distribution of technique of simulation application and each other , so simply introducing , as the forecast of the application of puter simulation in the manufacturing industry . 3 The concrete application in the manufacturing industry of puter simulation towards the simulation of product Simulation towards the product chiefly includes the following aspect: 1） The analysis of the static state of product and dynamic capability. The quieting of product chiefly indicates the mechanics property such as stress and intensity etc The dynamic characteristic of product is when chiefly indicating the product sports , the connection and colliding between the organization 2） The manufacturability analysis (DFM) of product. The DFM includes that the technology is analyzed and is analyzed with economy. The technology is analyzed the production environment to ask reaching reality according to the product technology and is carried on the analysis to the manufacturability pletely The economy is analyzed carrying on the cost analysis, and according to the feedback factors such as time and cost etc , the economy to part process is appraised . 3） Assembly nature analysis ( DFA ) of product. Analysis of DFA39。s ( aftersale service ) and E ( pollution of the environment level ) give first place to to weigh the product of quota and product development course , the United States has put forward including system overall technology , management technology in the 8039。s at a high speed along with the economy technology and market environment . The advanced manufacture technique ( AMT: the manufacturing integration technology that in order to improve with T39。 2. Interactive, due to technology of graphics and sensorymotor。 3. Integrated, such as VM, VPD, VFT, etc. According to different objects to be simulated, simulation in manufacturing can be classified as: 1. Productoriented 2. Productionmanagementoriented。s ( developing period ) , Q39。s ends and design , manufacture technology and equipment technology and big technology crowd of support technology five Advanced Manufacturing Technology ) the generally thought . As a result of the development of ten remaining years, now the content of five big technology crowds is arrived richly greatly, his concrete meaning as follows [ 12 ] : System overall technology crowd: Study the overall technology such as design, planning and integration etc like flexible manufacturing, puter integrated manufacturing, quick manufacturing and intellect manufacturing etc advanced manufacture techniques Technology crowd is managed: Study and makes the various technology of the production management of enterprise and organization and administration correlation, if puteraided production control and thing material requirement plan /39
