【摘要】：针对四配流窗口轴向柱塞马达实验成本高、研发周期长,提出了建立四配流窗口轴向柱塞马达虚拟样机仿真实验方法。首先利用Recur Dyn和AMESim软件建立四配流窗口轴向柱塞马达的3D动力学模型和1D液压系统模型;利用ANSYS软件,对四配流窗口轴向柱塞马达部分几何模型进行模态求解,生成四配流窗口轴向柱塞马达模态柔性体(R-Flex)多柔体动力学模型;利用Recur Dyn和AMESim软件间接口技术,实时传递与共享机械系统模型和液压系统模型间的关键参数信息,完成虚拟样机模型构建;最后通过动力学求解,得到四配流窗口轴向柱塞马达在不同工况下的动态应力应变,实现四配流窗口轴向柱塞马达虚拟样机仿真实验。为四配流窗口轴向柱塞马达的实验研究、特性分析、结构优化及疲劳可靠度预测等提供重要参考和依据。
[Abstract]:The experimental cost of axial piston motor with four distribution window is high and the research and development period is long. A virtual prototype simulation method of axial plunger motor with four distribution windows is proposed. Firstly, Recur is used to simulate the virtual prototype of axial plunger motor. The 3D dynamic model and 1D hydraulic system model of axial plunger motor with four distribution windows are established by Dyn and AMESim software. By using ANSYS software, the partial geometric model of axial piston motor with four distribution window is solved, and the multi-flexible body dynamic model of flexible body R-Flex of axial piston motor with four distribution window is generated. Using the interface technology between Recur Dyn and AMESim software to transfer and share the key parameter information between the mechanical system model and the hydraulic system model in real time, the virtual prototype model is constructed. Finally, the dynamic stress and strain of the axial piston motor with four distribution windows under different working conditions are obtained by dynamic solution. The virtual prototype simulation experiment of axial piston motor with four distribution window is realized, which provides an important reference and basis for the experimental research, characteristic analysis, structure optimization and fatigue reliability prediction of axial piston motor with four distribution windows.
