Speed characteristics analysis and simulation of the water hydraulic axial piston motor

摘要

Purpose - The purpose of this study is to analyze the speed characteristics of the water hydraulic axial piston motor. The speed performance of water hydraulic piston motor which uses water as medium is different from that mineral oil one. Design/methodology/approach - To analyze the speed characteristics of the water hydraulic motor, the speed model of a swash plate water hydraulic piston motor is developed theoretically and a simulation model with AMESim is built. Findings - The effects of clearance between friction pairs and input pressure on the speed are analyzed and compared between the theoretical and numerical models. Originality/value - The results of the theoretical and simulation models both verify that the clearance of friction pairs is the key factor in the hydraulic piston motor's speed.
