Modeling and simulation analysis of radial piston motor with inner curve based on AMESim

To reduce the manufacturing cost of the physical prototype during R & D and reduce the testing time. This article establishes a simulation model of variable displacement radial piston motor with inner curve based on AMEsim. The three operating conditions of the hydraulic motor under full displacement, half displacement and their mutual switching are simulated. The results show that under the condition of full displacement and half displacement, the torque and speed of the inner curve radial piston motor can quickly reach stability, indicating that the design meets the requirements and has high reliability. When the working conditions of full and half displacement are switched, the torque and speed fluctuate to a certain extent. It shows that there is an impact at the specific position of the curve, which needs to be further optimized to improve the stability.
