The finite element model of lower control arm beneath vehicle’s suspension was established. In static analysis of the model, inertia relief principle was introduced to eliminate the stress concentration effect of the constraint reaction force on the structural strength of the control arm. In this method, the acceleration due to the unbalanced loads was calculated. The static stiffness properties of the control arm were analyzed. The breaking load and buckling load of the suspension control arm under the conditions of tension and compression were calculated respectively. The results demonstrate that the static stiffness and strength characteristics of the control arm can meet the design requirements.
