2.In mechanical engneering,whether the choice of the original parameters and the designing of structural parameters are reasonable determines the quality and the various functions of a product. This paper,proceeding from the optimum way of design and taking full account of the structural features of the archgradated roller gear cam mechanism,uses multiobjective optimization and the WHP method to achieve the parameter optimization of the roller gear cam mechanism.
在机械工程中，原始参数的选择和结构参数的设计是否合理决定了产品的质量和产品各方面性能的优劣，从优化设计思想着手，充分考虑到弧面分度凸轮机构的结构特点，采用了交互式多目标优化方法——权空间法，并将此方法与约束变尺度（WHP）法相结合，进而解决弧面分度凸轮机构参数优化设计的问题。收藏指正
