	Dynamic optimum design and analysis of cam wave generator for harmonic gear drive (EI CONFERENCE) 会议论文 OAI收割 2011 International Conference on Information and Automation, ICIA 2011, June 6, 2011 - June 8, 2011, Shenzhen, China Xiao Q.; Han X.; Jia H. 收藏 \| 浏览/下载：22/0 \| 提交时间：2013/03/25 Mathematical models of structural optimization were established for the cam wave generator then a conceptual model by integrally taking its static and dynamic performance into consideration which satisfied the model acted by four concentrated forces while the dynamic optimum design was carried out. The topology optimization of the cam wave generator was performed based on artificial material density method was obtained. And the size optimization of the cam wave generator was also executed based on the zero-order method in software Ansys after setting up its parameterized model. The optimized results indicate that its final volume declines to 1284.217mm3 from its 1397.830mm3 which reduced by 42.18% than the original volume of cam (2221.224mm3). Simultaneously the static analysis and modal analysis were implemented and the results show that the static and dynamic performance complies with the design requirements proving that the results of dynamic optimum design are reasonable. The optimized results in paper are realizable in engineering. And the study method provides not only a reference to decreasing design mass and lowering inertia of the cam wave generator but also an important basis of lightweight design of harmonic gear drive. 2011 IEEE.
