Stress and Deformation Analysis of a Swash Plate Type Variable Displacement Axial Piston Pump Through Solidworks Environment

Swash plate type variable displacement axial piston pump is a very reliable source of power for a hydraulic power and control system. This paper focuses on the stress and deformation analysis of the various important parts of the axial piston pump at different conditions. Stress and stress concentration is one of the causes of vibration, noise of the pump, and failure of the pump components . This research work provides a theoretical analysis of stress and deformation of important components directly related to the pump body such as barrel piston, retainer plate, and piston shoe. A pump with pressure compensator model has been coded in the solidworks environment considering some standard design parameter. The proper dimension and selection of materials are a very important issue in the design point view. Some design suggestion and some critical issue are recognized from this analysis.
