基于缸径与流量匹配的高空作业平台飞臂液压系统节能设计
Energy-saving Design of Aerial Work Platform Flying Boom Hydraulic Systems Based on Cylinder Diameter and Flow Matching
摘要
Abstract
Aiming at the problems of very low efficiency of the aerial working platform flying arm hydraulic systems,a new method was proposed to reduce the energy consumption of the hydraulic systems by matching the hydraulic cylinder bores of the flying arms and the output flow rates of the pump.A mathematical model of the load apllied on the flying arm mechanisms was established,and the simulation model of the aerial working platform flying arm hydraulic systems was established by AMESim software,and the energy consumptions of each design scheme were calculated on the basis of verifying the accuracy of the simulation model through experiments.The results show that:under the premise of ensuring that the actuator load and output speed of the flying arm hydraulic systems are unchanged,by matching the hydraulic cylinder bores of the flying arms and the flow rates of the pump,and the load-sensitive pump is avoided to work in the small-displacement areas.The efficiency of the hydraulic systems may be effectively improved,and the overall efficiency of the optimized flying arm hydraulic systems is improved by 4.6％.关键词
