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.

In computer graphics applications  mesh coarsening is an important technique to alleviate the workload of visualization processing. Compared to the extensive works on static model approximation  very little attentions have been paid to animated models. In this paper  we propose a new method to approximate animated models with local area distortion and deformation degree control. Our method uses an improved quadric error metric guided by a local area distortion measurement as a basic hierarchy. Also  we define a deformation degree parameter to be embedded into the aggregated quadric errors  so areas with large deformation during the animation can be successfully preserved. Finally  a mesh optimization process is proposed to further reduce the geometric distortion for each frame. Our approach is fast  easy to implement  and as a result good quality dynamic approximations with well-preserved sharp features can be generated at any given frame. 2010 SPIE.
