摘　　要：分析了液压变压器的工作原理,利用AMESim软件对液压变压器进行建模、仿真和分析,得到配流盘在不同控制角度下液压变压器的输出压力曲线。结果表明,在考虑粘性摩擦和泄漏的情况下,液压变压器实际变压比曲线与理论曲线不一致,存在最大变压比;稳态输出压力脉动和动态输出压力冲击可控制在合理范围之内。This paper analyzes the principle of hydraulic transformer （HT）. The modeling, simulation and analysis of HT are established and accomplished in AMESim. The output pressure curves of HT under different control angles are obtained. Simulation results show that the real transformation ratio is not in accordance with the theoretical curve and a maximum value exists if the viscous friction and leakage are taken into account, and the steady output pressure pulsation and dynamic output pressure impact could be controlled in a reasonable zone.
