Abstract

In this paper, the numerical analysis is introduced to predict the dynamic characteristics of piston pump assembly components in hydraulic piston pump for aircraft. Rotating cylinder block and reciprocating pistons are modelled kinematically. Furthermore, leakage flow and torque losses between the boundary surfaces of components are analyzed. This analysis has been carried out through the commercial CASPAR program. The simulations for stress on pump assembly components using the dynamic analysis model are performed using the ANSYS 11 program. Such dynamic characteristics and stress simulation procedures will be carried out repeatedly for the optimized design.
