Abstract
The swash-type piston pump is a device that discharges as much volume of hydraulic oil generated as it moves the ramp by controlling the angle of the swash. This pump is suitable for high-speed high pressurization, and due to its useful characteristic being the variable capacity-type, it is used as a main pump for heavy equipment in various fields such as defense, shipbuilding, construction, etc. This study intends to obtain optimal design values by conducting a structural analysis in order to verify its reliability during the design process of the newly developed swash-type piston pump.
