直线往复运动的固定凸轮连杆机构的优化设计

Optimal Design of Rectilinear Reciprocating Mechanism of Fixed Cam and Linkage

本文对直线往复运动的固定凸轮连杆机构的特点进行了分析与讨论,提出了以机构纵向尺寸为目标函数,平均效率为传动质量指标,适当限制压力角的优化设计方法,并对它进行设计。本文还对机构的传动质量指标进行了探讨,得到了能适用于一般基本机构的传动质量指标公式。

In this paper, the characteristics of rectilinear reciprocating mechanisms of fixed cam and linkage are analysed and discussed. The optimization method is presented by which the longiludinal size is served as object function, the average efficiency as the transmission quality index, and pressure angle as limit condition, The optimal design of this kind of mechanism is completed. The transmission quality index of mechanism is also discussed in this paper and a normal formula of transmission quality index for the general basic mechanisms is obtained.
