Simulation Study on Dynamic Characteristics of Hydraulic Steering System of Load- Haul-Dump Unit with Accumulator

The hydraulic power steering system(HPSS) of EIMCO model 922 load-haul-dump unit (LHD) is used as a simulation example, then the dynamic characteristics of HPSS of LHD are simulated and discussed with SIMULINK software and hydraulic control theory in the paper. The simulation results provide theoretical basis for designing HPSS of LHD.
