Short summary
In order to reduce the energy loss and improve the wear resistance of a piston–cylinder pair in an axial piston motor,an optimized tapered piston bore is designed and applied. A fluid–structure interaction numerical model and a new test rig of the friction force of the piston–cylinder pair are developed. Numerical analysis and experimental results show that the optimized tapered-shape piston bore in an axial piston motor can achieve a significant reduction in leakage flow and friction force.
