含间隙机构无质量杆-弹簧阻尼组合模型的近似解法

Approximate solving method on Massless-Link and Spring-Damper (MLSD) model of mechanism with clearance

提出了一种新的无质量杆 -弹簧阻尼组合 (MLSD)模型非线性动力学运动微分方程的近似解法。它通过求解无间隙机构来得到相应的含间隙机构的动力响应 ,无须求解系统的非线性微分方程组 ,使解决问题的难度大为降低 。

A kind of approximation method for the solution of differential equation of nonlinear dynamics motion in MLSD model was advanced. By means of solving the non-clearance linkage, this method obtained the corresponding kinetic response of mechanism with clearance, and need not to solve the non-linear differential equation set of the system, thus greatly reduced the difficulty of solving this issue and possessed a fairly high precision.
