摘要
基于油压缓冲器的工作原理,建立小型多孔式缓冲器AMESim模型。缓冲器活塞在运行过程中通过逐渐遮蔽内缸筒壁上的节流孔来改变节流面积,从而使冲击物的速度平稳降低,起到缓冲作用。通过仿真分析,得到油压缓冲器在缓冲和复位过程中的冲击物速度、位移、加速度变化曲线以及缓冲力变化曲线。仿真结果表明油压缓冲器能满足实际工况的应用要求,为油压缓冲器的优化和设计提供了参考。
Based on the working principle of the hydraulic buffer,an AMESim model of a porous buffer was established.During the operation of the bumper piston,the throttle area is changed by gradually covering the throttle hole on the wall of the inner cylinder,so that the speed of the impact object is reduced steadily,and the buffer effect is played.Through simulation analysis,the velocity,displacement,acceleration change curve and buffer force change curve of the shock absorber during the buffer and reset process are obtained.The simulation results show that the oil pressure buffer can meet the application requirements of actual working conditions,which provides a reference for the optimal design of the oil pressure buffer.
