摘要: 以变长度曲柄-连杆机构为研究对象。从弹性力学分析入手,建立了变长度曲柄-连杆机构的非线性动力学模型;用数值计算方法对非线性动力学方程进行了求解。实例计算的分析结果表明:选择适当地变化规律,改变曲柄长度,可以降低机构的动态响应。这为振动响应的控制研究开辟新的思路。

关键词: 弹性连杆, 动力学分析, 动态响应

Abstract: A mathematical model of an elastic linkage is developed, in which the length of the crank is variable. An algorithm is developed to solve the dynamic equations of the mechanism. Through an example, it is demonstrated that the dynamic response can be reduced by adjusting the length of the crank. Thus, a new method is suggested to improve the dynamic performance of elastic linkage mechanisms.

Key words: Dynamic response, Elastic linkage mechanism, Kineto-elastodynamics analysis
