The Integrated Environment Of Virtual Prototyping Technology Research And Its Applications

As a new technology of product design, Virtual Prototype is a revolution to traditional method of products design. Based on Virtual Prototype, engineers can find underlying problems just during products design by simulating the mechanical system, and revise them quickly so as to throw off the Physical Prototype, which not only can save the cost of design and manufacturing and reduce the cycle of products development, but also can elevate products' performance and enhance products' competition.The thesis studied in the paper roots in the demonstration project of the modeling and reality of the virtual prototype for numerical control machine tool under the integrated environment. The paper applied virtual prototype technology to the design of machine tool. It studies the integrating methods and technology among the characteristic modeling, kinematics analysis and finite element analysis system and establishes the virtual prototype of XK6420 numeric machine tool.At first, according to the design requirement, use large-scale three-dimensional software Solid Edge to set up the three-dimensional parameter entity's model of the numeric machine tool. Through the graphics interchange format of computer, introduce the geometry models established into ANSYS and ADAMS/View. Then the prototype of numeric machine tool is established.Through adopting the technological analysis of ADAMS, analyze the numeric machine tool of XK6420 action force between every main attachment under various operating conditions, so offer the border condition for the finite element analysis; through the finite element analysis about the assembly structure intensity on the numeric machine tool, receive high stress and dangerous area that meet an emergency. Then optimize the structure to this area, and the result indicates that the working condition is improved obviously on this component, '['hereby guarantee the running reliability of the whole machine.The method of building Virtual Prototype and Finite Element Analysis is theoretically meaning and practically valuable for design and performance simulation of complex mechanical system.
