Abstract

The elevation-balancing machine is used to give the elevation angle of the landing parts of the rocket launcher, and the three-chamber hydraulic cylinder is the power device in the system. In order to obtain the dynamic characteristics of cylinder reasonably and scientifically, considering the flexible characteristics of the movable piston barrel, building a 3D model of the three-chamber hydraulic cylinder through SolidWorks software, generating a modal neutral file of movable piston barrel's flexible body in ANSYS, creating a rigid-flexible coupling analysis model and simulated in ADAMS, to obtain the corresponding actuator output curves and kinetic parameters. According to the comparison of the simulation results,, the lateral dynamic characteristics of rigid-flexible coupling model compared with the rigid conditions have certain changes, the rigid-flexible coupling model can more accurate response the three-chamber hydraulic cylinder's working process. It shows that the rigid-flexible coupling model established by finite element method has higher accuracy, more in line with the needs of the study.
