Abstract

Abstract

To better the wear condition of the piston/bushing interface, the fluid-structure model was created, the interaction between fluid domain and solid domain was studied, the elastic deformations of the piston and bushing were considered, the impact of different thickness of bushing and material with different elastic moduli on the film thickness and deformations of bushing was discussed. The results show that the deformations of bushing decrease with increasing modulus of elasticity, bushing of copper lining materials with smaller elastic modulus or increasing of thicknesses of the bushing properly can improve lubrication conditions of the piston/bushing interface and the service life of the piston pump. Elastic deformations of piston and bushing have significant influences on the film thickness. The results provide a reference for the optimization design of the piston pumps.
