This paper provides a methodology for extracting design data from the three-dimensional design software SolidWorks<SUP></SUP>®<SUP></SUP>, which isbased on the existing trochoid pump design equations thatare used by hydraulic field engineers. The data extracted from the SolidWorks<SUP></SUP>®<SUP></SUP> model are input to a hydraulic analysis software AMESim<SUP></SUP>®<SUP></SUP> model todetermine the design factors that can influence the properties of a trochoid pump. On the basis of the simulation results, this paper proposesa methodto reduce the flow loss by adjusting the outlet angle of the trochoid pump. This proposal was verified by using actual experimental results, which confirmed that adjusting the outlet angle can increase the flow rate. Hence,the results presented in this paper can contribute to the prototyping of a trochoid pump by reducing the cost associated with a trial-and-error design.

Flow rate control is the uppermost concern for a trochoid hydraulic pump. Cavitation within the flow field of the pump has the greatest effect on the flow control during high-speed pump rotation of approximately 3500~4000 RPM. In this paper, based on AMESim<SUP>®</SUP> and Solid Works<SUP>®</SUP> , we will present a method to simulate cavitation by analyzing the control factors of a trochoid pump, including the hydraulic pressure change at the outlet, flow rate based on the rotation speed of the inner rotor, leakage through the gap between the outer and inner rotors, and discharging angle of the outlet. The proposed methodology of the [cavitation simulation will enable field engineers to more easily design trochoid pumps, and will allow more concrete control over the flow rate of the pump by realizing an analysis model similar to the actual product model.
