摘要
针对液压挖掘机中使用的LUDV控制系统,利用AMESim软件建立了该系统的仿真模型,并对其负载特性做了计算,获得节流阀进出口压差、流量、脉动及效率等特性曲线,最终验证了LUDV系统的控制特性。通过对其负载特性的分析得出:在多负载且系统压差增大时,LUDV系统的脉动增大、效率降低。
Aiming to the LUDV control system of hydraulic excavators, this paper uses the software AMEsim to build up a simulation model ,calculates it＇ s loading characteristic and obtains some performance datum of pressure, flow, pulse and efficiency. Finally, the control characteristics of the LUDV system are verfied. Through analysing the load characteristics we know that when the system is in a multi - load and increased pressure case, the pulse of the system is increased, but the efficiency is reduced.
