摘　　要：多孔式缓冲液压缸作为一种被动控制、无需外部能源输入的缓冲装置,日趋应用于越来越多的大功率重载缓冲工况。以某重载特种机械提出的到位缓冲需求为基础,通过对多孔式缓冲液压缸的阻尼力进行数学建模、仿真分析和试验验证,对比研究了其缓冲效果,最后结合实际工况,验证了其缓冲效果的可靠性。As a buffer device with passive control and no need for external energy,the porous buffer hydraulic cylinder is utilized more and more high-power and heavy-load buffering conditions.In this paper,based on the in-place buffer requirement of a heavy special machinery,the damping force of the porous buffer hydraulic cylinder is studied by mathematical modeling,simulation analysis and experimental verification.Finally,the reliable of the buffer effect is verified according to the actual working condition.
