Flow rate control is the uppermost concern for trochoid hydraulic pump. Cavitation within the flow field of pump has the most influence on flow rate control reason at approximately 3500 ∼ 4000 RPM high speed rotation of pump. In this paper, based on AMESim® and CATIA®, we will present how to simulate cavitation by analyzing the control factors of trochoid pump; hydraulic pressure change of outlet, flow rate according to rotation speed of inner rotor, leakage through gap between outer rotor and inner rotor, and discharging angle of outlet. The proposed methodology of cavitation simulation will enables field engineers to have access to the design of trochoid pump more easily and thereby to have more concrete control over the flow rate of pump by realizing its analysis model similar to its actual product model.
