摘　　要：利用Matlab/Simulink对单缸驱动液压电梯的简化模型进行仿真分析,得到不同频率的简谐激振力激励下的加速度响应曲线。仿真结果表明,在柱塞行程中部时其共振频率较低,当激振力频率与共振频率相差较大时液压电梯运行比较平稳。In this paper, the simplified model is simulated for single-cylinder drive hydraulic elevator based on Matlab/Simulink software, the acceleration response curve caused by the different frequency stimulation force is investigated. The simulation results show that in the middle of the plunger stroke, the resonance frequency is small, the hydraulic elevator runs smoothly when the difference is bigger between excitation frequency and resonance frequency.
