基于ADAMS软件的仿真平台,采用接触碰撞力模型和间隙摩擦力模型模拟含间隙运动副,并以曲柄摇杆机构为研究对象,研究多运动副间隙对机构动力学性能的影响。含单运动副间隙对机构速度影响不大,使加速度产生波动;含双运动间隙会加剧对机构动力学性能的影响,加速度产生更大的波动,更加接近与机构的真实运动情况,为机构设计提供更可靠的参考。
Based on the simulation platform of ADAMS, the model of contact force and the model of gap friction are used to simulate the kinematic pair with gap, and the mechanism of the crank and rocker is taken as the research object to study the influence of multiple clearances on the dynamic performance of mechanism. The gap with single movement has little effect on the velocity of the mechanism, which causes the acceleration to fluctuate. The double movement gap will aggravate the influence on the dynamic performance of the mechanism. The acceleration produces greater fluctuation and closer to the actual movement of the mechanism, Provide a more reliable reference.
