Performance Analysis of Inner Curve Radial Piston Motor Based on ADAMS
In order to investigate the influence of different forms of inner curve guide on the performance of radial piston motor,the trajectory equation of inner guide curve of radial piston motor using tangent arc as inner guide curve was solved by mathematical analysis method,and the radial motion of piston was studied.At the same time,according to the relevant dimensions of the circular arc curve guide,the equal acceleration inner curve guide rail which could be replaced with it was designed.The dynamic model of the motor guide,piston plate,piston and rolling pin were constructed by ADAMS software to verify the rationality of the acceleration curve design.On the basis of theoretical analysis,coupled with dynamic simulation methods,the piston motion under the two curve forms was com-pared,and the impact of different guide curves on the motor performance was analyzed.The simulation results show that under the same boundary conditions,the selection of different curved guides will directly affect the transient acceleration variation of the piston under high-pressure hydraulic action.The adoption of a suitable internal curve guide can reduce the impact of the piston on the guide,reduce vibration and improve the stability of the motor.
