| Abstract: | 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. |
