摘　　要：以弹性四连杆机构为研究对象 ,综合考虑机构质量和声辐射性能两项指标 ,对以杆件厚度为设计变量的机构结构参数优化问题进行了讨论 。The problem of noise attenuation of a flexible four bar mechanism is studied in this paper. The mass and acoustic radiation performance are taken into consideration, and the thicknesses of the links of the mechanism are taken as design variables. Then the optimal design of structural parameters of mechanism based on noise attenuation is discussed. Finally, simulation is carried out to verify the method presented in this paper.
