Abstract	In order to improve efficiency/productivity and thus facilitate work at industry sites, hydraulic system uses hydraulic fluid and has higher power density than other power transfer systems. A swash plate type variable piston pump among hydraulic equipment is the most important and basic component composing the hydraulic system, which plays a role of converting mechanical energy into fluid energy. This paper focuses on the simulation technique that can estimate the reduction effect of the pressure/flow pulsation depending on analysis of pulsation variables and notch shape of valve plate of swash plate type variable piston pump. First, we will consider the theoretical kinematic analysis according to the variable swash plate angle and rotational velocity in order to design single piston pump using $SimulationX^{®}.$ Based on this kinematic analysis, we will analyze the pulsation variables such as piston diameter, maximum piston stroke including the swash plate angle and pitch circle diameter of swash plate type variable piston pump. Also, in designing the notch shape of valve plate of swash plate type variable piston pump as one of pulsation variables, we will investigate the effect of pulsation by comparing with two type notches (circular type vs. V type). Similarly we will analyze the pressure/flow pulsation notch types in nine piston pump model, which is mainly designed for the actual swash plate type variable piston pump. This paper not only can confirm that effect of the pressure/flow pulsation according to pulsation variables but also can be referred to as the development of $SimulationX^{®}$ based simulation technique to be applied to notch shape optimization for a swash plate type variable piston pump.
