含间隙机构混沌响应的实验研究

Experimental Research on the Chaotic Responses of Mechanisms with Clearances

通过实验证明了含间隙连杆机构的动态响应具有混沌特性，动态响应的混沌程度受机构输入速度和运动副间隙大小的影响。虽然机构在各个运动循环的动态响应不重合，但动态响应的典型形式是存在的，实验结果为检验数值计算的正确性提供了依据。

It can be seen from experimental results that the dynamic responses of a mechanism with clearance connections are chaotic. The chaotic state is influenced by the input speed and the clearance size of the mechanism. Although the dynamic responses of a mechanism with clearances are nonperiodic and the initial condition is sensitive, typical response patterns do exist. The experimental results can also be used to verify the accuracy of the numerical calculations.
