摘　　要：为解决装载机夏天工作中液压系统过热问题,提出了将集总参数法用于液压系统解决传热问题的方法。采用集总参数法,建立液压系统传热问题的RC网络传热模型,编制计算程序。对某50型轮式装载机液压系统传热进行了仿真计算,并比较了仿真结果和试验数据。结果表明:采用集总参数法研究装载机液压系统的传热问题,其仿真结果的精度能够满足工程要求,模型的准确度满足工程设计需要,对液压系统的设计和改进具有指导作用。In order to solve the overheating problem in the hydraulic system of loader working in summer,the lumped parameter method is introduced to study the heat transfer in the hydraulic system.A RC network of heat transfer model is established using the lumped parameter method,and the computational program is developed.The heat transfer in the hydraulic system of a 50 type wheel loader is simulated,and the simulating results are compared with test data.Results show that the simulation precision can satisfy engineering demand and the accuracy of the model can meet the needs of engineering design.This study provides valuable reference to the design and improvement of the hydraulic system of loader.
