Abstract

This paper presents the design optimization result of anchor shape with design of experiments (DOE) and magnetic-fluid-system co-simulation technology for designing a quieter high-pressure pump. Since the impact noise level increases with increasing valve impingement velocity, the objective of design optimization is to reduce the valve impingement velocity. In this study, we executed the DOE to simulate the anchor/core impingement velocity with oblique model and four design parameters. In addition, we also compared the impingement velocity results between which obtained by DOE and which obtained by original shape, evaluated the four design parameters with factor effect diagram and obtained following results. 1)The anchor impingement velocity which obtained by on two of nine models is slower than the original shape and. 2) The flat surface length(l2) of the anchor mostly affected the fluid force acting on the anchor in the oblique model. The length also mostly affected the solenoid force acting on the core and the anchor-core impingement velocity.
