摘要

针对工程机械回转机构能耗大的问题,分析了四配流窗口轴向柱塞液压马达实现回转执行机构能量回收方法的原理。物理样机实验对泄漏和内部接触应力研究存在一定困难,且样机试制成本高、周期较长。鉴于以上情况,提出一种机液耦合仿真分析实验方法。通过AMESim和RecurDyn共同联合搭建仿真平台,得到四配流窗口轴向柱塞马达对应于不同工况下柱塞副、滑靴副间的的瞬态应力应变。仿真结果表明,四配流窗口轴向柱塞马达结构设计合理,并验证了联合仿真方法的可行性,为后续结构改进优化提供参考依据。

Abstract

Aimed at high energy consumption of rotary mechanism of construction machinery, the energy recovery principle of four assignment windows axial piston motor were introduced. It is difficult to implement the research on leakage and internal contact stress by the method of physical prototype experiment, and products preparation is restricted by the long period, high cost and condition. In view of the above, the method by coupling simulation of machinery and hydraulics are suggested. Through the joint simulation platform of AMESim and RecurDyn, the transient stress and strain of piston pair and slipper pair were obtained under different working conditions. Simulation results show that the structural design is reasonable, and the feasibility of the joint simulation method is verified. It is a useful reference to the structure optimization for future research work.
