摘　　要：为得到准确的含间隙铰接机构的接触碰撞模型,在ADAMS中建立含间隙的曲柄滑块机构,以含间隙曲柄滑块机构运动副为对象分析其在考虑磨损情况下的动态特性。以接触-碰撞模型为基础,采用非线性等效弹簧阻尼模型,将用MATLAB处理过的数据和磨损函数嵌入到ADAMS模型中进行动力学仿真,并将得到的动态特性曲线进行分析。结果表明:磨损对间隙运动副的速度、加速度、接触碰撞力和力矩有很大的影响,同时,此种建模方法对建立准确的含间隙机构的模型有很大的参考意义。In order to get the accurate contact model of articulated mechanism with clearance, the slider-crank mecha- nism with clearance model is built in the ADAMS, taking the clearance joint as the object to analyze its dynamic char-acteristics with considering the wear situation. On the basis of collision model, using the nonlinear equivalent spring damper model, then using MATLAB to dispose the data and implanting the wear function into the ADAMS model.Through analysis the dynamics simulation curve, and the results show that the wear of joint with clearance has a great influence to the speed, acceleration, force and toque, and also the modeling approach of this paper has great signifi- cance reference to establishing an accurate model of mechanism with clearance.
