摘　　要：为了改善剪叉式升降台初始启动和末端停止时出现的速度突变现象,提出一种基于液压缸行程的分段液压调速方案。以某三级剪叉式升降平台为研究对象,分析平台升降速度与液压缸伸缩速度之间的关系,设计相应液压回路,并利用AMESim软件进行了仿真验证。结果表明:在保证升降效率的前提下,采用分段速度调节可有效减小初始启动和末端停止阶段的速度突变。To improve the sudden change of scissor lift speed at start-up and end-stop,a new speed regulation scheme based on hydraulic cylinder displacement is proposed.Taking a three-stage scissor lifting platform as the research object,the relationship between the hydraulic system flow rate and the lifting speed is deduced.The corresponding hydraulic circuit is designed.Using AMESim software,the speed regulation characteristics of the lifting platform are analyzed by simulation.The results show that the lifting speed sudden change in the initial start-up and end-stop stages can be effectively reduced adjusting the proposed speed regulation scheme,while the work efficiency is assured.
