用无质量杆-弹簧阻尼组合模型(MLSD模型)对间隙机构进行分析的方法探讨

Mehhod Study by Using Massless-Link and Spring-Damper Model(MLSD Model) to Analyse the Linkage Mechanism With Clearance

通过用MLSD模型对含间隙四杆机构进行分析 ,提出了一种新的解该模型非线性动力学运动微分方程的近似方法 这一方法无须求解系统的非线性微分方程组 。

A new approximate method of solving MLSD model equations is obtained by theoretical analysis to four-bar mechanism with clearance. The new method does not need to solve directly the non-linear motion differential equations of system,but needs shorter computation time and has an acceptable precision.
