Abstract

This paper describes the analysis of state when load applies to McPherson strut assembly. Strut assembly except knuckle-arm are created with 3 dimensional modeling program. Stress and structural strength on this model are analyzed by analysis program as load applies on the lower part of assembly modeling. When McPherson suspension is applied with 3000N at Z direction, maximum stress at spring becomes 433MPa and the cycle of minimum life is 4321. The designed modeling suspension at this study has no possibility with resonance.
