Abstract  

Modeling and simulation were conducted for swash-plate axial variable displacement piston pump. The pump is a key component in hub-motor hydraulic driving system. Motion equations for key parts of the swash-plate axial variable displacement piston pump were established based on kinetics analysis. The model was consructed in AMESim, and the displacement response characteristics of the swash-plate axial variable displacement piston pump under different PWM duty cycles were simulated. The simulation results were compared with the experimental results. Results showed that characteristics of the model achieved a high level of compliance with the real pump. It is easy to get pump models with different response characteristics by changing some parameters. Simplification of nonlinear dynamical problems in the modeling process saves costs of actual test and cycles by avoiding difficulties in the practical test system.

轮毂液驱车辆泵控系统建模

针对轮毂液驱混动系统当中关键部件：斜盘式轴向柱塞变量泵的动态特性进行建模仿真与试验对比分析.通过对斜盘式轴向柱塞变量泵进行力学分析，建立柱塞泵关键部件的运动方程.在AMESim中搭建模型，对斜盘式柱塞变量泵在不同脉冲宽度调制（PWM）占空比下的排量响应特性进行仿真，将仿真结果与试验结果进行对比分析.结果表明：搭建的AMEsim模型与实际斜盘式轴向柱塞泵的响应特性高度吻合，通过参数调节可以快速得到具有不同响应特征的泵控系统模型.建模过程中对非线性动力学问题的简化，避免了在实际系统中进行测试的困难，节省实际测试的费用和周期.
