摘要: 运动副元素分离准则是含间隙机构动力学的重要研究课题,它将为避免运动副元素的碰撞、减小机构噪声和延长机构寿命的研究奠定理论基础,具有重要意义。本文通过理论分析,提示了原有准则的缺陷,提出了新的较完善的运动副元素分离准则,其正确性通过对一含间隙平面四杆机构的数值计算得到了验证。

Abstract: The criterion of contact loss between pairing elements is an important problem in the field of dynamics of mechanism with clearances. It is the theoretical basis for the design of avoiding impacts, reducing noises and prolonging the life of mechanisms. According to theoretical analyses, this paper points out the deficiencies of the oriterien which is now used and puts forward a new, more effective criterion. The correctness of this new criterion is verified by calculating the dynamic response of a planar four-bar mechanism with clearances.
