摘　　要：基于动力学仿真软件,对含间隙曲柄滑块机构进行动力学分析,研究不同间隙大小的铰链在干摩擦条件下和无摩擦条件下对曲柄滑块机构动态响应的影响。搭建曲柄滑块机构实验台,通过实验,研究干摩擦条件下和充分润滑条件下不同间隙大小的铰链对曲柄滑块机构动态响应的影响。研究表明,铰链摩擦、间隙大小和转速高低,对曲柄滑块机构的动力学特性均有影响。Based on dynamics simulation software, the dynamics analysis of the slider- crank mechanism with clearance joint is carried out and the effect of joint with different clearance size under dry contact and non - friction conditions on dynamic response of slider - crank mechanism is researched. A slider - crank mecha- nism test rig is built, through experimental, the effect of joint with different clearance size under dry contact and fully lubricated conditions on dynamic response of slider that joint with clearance lubricated or not, clearance size slider - crack mechanism. -crank mechanism is researched. The studies show and speed have an impact on the dynamic response of
