以提高多缸液压升降装置的稳定性为目标,设计一种多缸液压升降装置的智能控制系统。以液压缸、换向阀为硬件核心完成升降装置的液压系统设计,并利用FLuidSIM绘制了液压系统原理图;通过压力传感器、比例换向阀搭建一种具有比例反馈环节的智能控制系统,通过比例反馈环节对系统工作压力的有效控制,保持液压升降装置的稳定性;利用AMESim建立智能控制系统的仿真模型。通过对仿真结果的分析表明:智能控制系统减少了系统压力损失,保持了液压升降装置的所需压力,增强了液压升降装置的稳定性。

With the aim of improving the stability of multi-cylinder hydraulic lifting device,an intelligent control system of multi-cylinder hydraulic lifting device is designed.Hydraulic cylinder and reversing valve are adopted as the hardware core to design the lifting device hydraulic system,and the hydraulic system schematic diagram is drawn by FLuidSIM.With pressure sensor and proportional directional valve,an intelligent control system with proportional feedback link is built,and by proportional feedback link,the working pressure of the system is effectively controlled to maintain the stability of the hydraulic lifting device.And AMESim is applied to establish the simulation model of intelligent control system.The analysis on the simulation results shows that the intelligent control system reduces the pressure loss of the system,maintains the required pressure of the hydraulic lifting device,and enhances the stability of the hydraulic lifting device.
