quency (the parts under the harmonic force of 100 N) 4 ConclusionsBy use of the technology of virtual dynamic optimization design, the entire processes of products development are carried out under the visual virtual environment. This can bring products design and products development enormous convenience and superiority. Through bining the virtual reality with CAD technology, optimizing products design under the virtual environment, the application of puter technology to products design has been further widened, the dynamic performance of products structure has been optimized, and the development cycle has been shortened. So, this is an effective way to enhance the products designing level and to reduce the cost of products development.References參考文獻中請列出所有作者.期刊格式Wang Y X, Tai X M, Jiang S, 2001.
