摘要

为了研究间隙对铰接机构动态特性的影响,建立了一种改进的非线性接触碰撞的间隙动力学模型,通过修正接触碰撞参数,较准确地描述接触碰撞状态,然后将该模型嵌入到ADAMS中进行动力学仿真。针对某一铰接机构研究加载频率、加载加速度和间隙大小对其动态响应的影响。其仿真结果与实验结果的对比验证了模型的可靠性,为间隙机构动态特性研究提供一定的参考。

Abstract

In order to study the effect of joint clearance on the dynamic characteristic of the articulated mechanism,an improved nonlinear contact collision model is established. By modifying the contact collision parameters,the contact state of collision is accurately described. Then the model is incorporated into ADAMS for dynamics simulation. The effects of loading frequency,loading acceleration and clearance size on the dynamic response of an articulated mechanism are studied. Through the contrasts of simulation and experimental results,the reliability of the model is verified. Thus,a certain reference for the research of the dynamic characteristic of the articulated mechanism with joint clearance is provided.
