结构参量改变时弹性机构本征特性的研究

Study on the Intrinsic Properties of Elastic Mechanisms With Variable configuration Parameters

研究了改变结构参量对弹性机构内在特性的影响及其规律。首先以平面４Ｒ机构为例分析了机构杆件长度参数变化对机构固有频率和动应力等的动态响应。然后从参量与振动的关系的角度对数值计算结果进行了理论分析，由此得到了机构固有频率与结构参量之间的定性关系。

The intrinsic properties of elastic mechanisms are investigated in this paper by the way of changing configurational parameters.The dynamic responses of the natural frequencies and stresses of an elastic 4R linkage are demonstrared firstly,The numerical results are then discussed in the analytical way of parametric vibrational responses. The relationship between the natural frequency configurational parameters is derived to further illustrate the inherent characteristics of elastic mechanisms.
