Abstract

In a MacPherson strut suspension, which is one of the most popularly used vehicle suspension type, the side load is inevitably generated at the damper when wheel moves in the vertical direction. Since the side load causes friction at the damper and reduces riding comfort, it is important to reduce the side load for improving riding comfort. In this paper, an optimal design is performed to minimize the side load by using Kriging model. Before performing the optimal design, a flexible multi-body dynamics (FMBD) analysis, which can consider both multi-body dynamics and finite element method, is performed to verify the side load generated at the top of damper rod. As a result of optimal design, spring setting positions that minimize the side load are obtained and by using optimal spring setting positions, the suspension FMBD model was constructed.
