摘要
轴向柱塞泵在实际工作过程中会发生缸体倾覆现象,影响轴向柱塞泵的可靠性和寿命。为揭示缸体倾覆的原因,运用1D-3D联合仿真模型进行研究。分析了缸体x,y,z 3个方向上的受力情况及动力学方程。搭建轴向柱塞泵1D液压系统模型以及3D多体动力学模型,并通过接口实现仿真模型间的数据交互,得到完整的机液一体化仿真模型。对于不同工况下的缸体位姿进行仿真分析,结果表明:联合仿真模型能准确模拟缸体的受力情况,分析不同工况下的缸体位姿,可作为揭示缸体倾覆现象有力的分析工具。
The overturning phenomenon of cylinder block might occur in the actual working process of axial piston pump which affects the reliability and life time of axial piston pump.In order to identify the cause of the overturning of cylinder block,a 1D-3D co-simulation model is established for research.Firstly,analyzing the load conditions and dynamic equations with six degrees of freedom of the cylinder block.Secondly,a 1D hydraulic system model and a 3D multi-body dynamics model of the axial piston pump are built,and data interaction between the simulation models is realized through the interface to obtains a complete mechanical-hydraulic simulation model.Lastly,the dynamic movement of the cylinder block under different working conditions are simulated and analyzed.The research results show that the co-simulation model can simulate the load conditions of the cylinder block accurately,analyze the dynamic movement of cylinder block under different working conditions,and can be used as a powerful analysis tool for exploring the overturning phenomenon of the cylinder block.
