Considering the shape of a valve plate in design is important for reducing the pulsation phenomenon, which is a negative factor in pump performance. The purpose of this study is to propose an optimized method for a valve-plate V-type notch of a piston pump by modeling and simulation. The method uses SimulationX<SUP>Ⓡ</SUP>, a commercial hydraulic analysis program, and to provide data for the designing of the notch. The opening areas are determined by performing kinematic analysis of the notch part where the opening area changes rapidly. After applying the result analysis, the main effects on maximum pressure pulsation and maximum backflow according to the notch design factors are analyzed by using the full factorial method of experimental design. The optimized solutions are derived for the notch design variables, based on the analyzed data.

In the swash plate type pump, the driving shaft and the central axis of the cylinder block have a predetermined angle. In the swash plate type pump, the main shaft and the cylinder block are parallel to each other and have a predetermined angle through the swash plate. In this paper, the structural stability of a variable capacity swash plate type piston pump for a ship engine is analyzed by analyzing the flow rate and the ripple effect on the piston design element.
