在对轴向柱塞泵工作原理及运动学理论分析基础之上,建立柱塞泵ADAMS多体动力学模型和AMESim液压系统模型,通过软件接口实现多体模型与液压模型的联合仿真,创建柱塞泵液固耦合的虚拟样机模型。仿真分析柱塞的运动学特性,以及负载压力、斜盘倾角等参数对柱塞滑靴组受力状态的影响。结果表明,柱塞副的承载能力设计是柱塞泵压力极限和斜盘最大摆角的重要决定因素。
Based on the analysis of working principle and kinematics theory of axial piston pump, ADAMS multi-body dynamic model of piston pump and AMESim hydraulic system model are established. Combined simulation of multi-body model and hydraulic model is realized by software interface. Fluid - Solid Coupling Virtual Model of Plug Pump. The kinematic characteristics of plunger and the influence of load pressure, swash plate inclination and other parameters on the stress state of plunger sliding shoe are simulated and analyzed. The results show that the design of the load carrying capacity of the plunger pair is an important determinant of the pressure limit of the plunger pump and the maximum swashplate angle.
