ABSTRACT

Stabilizer bar is an important component of the vehicle’s independent suspension system and plays an important role in the safety traffic. Therefore, the research on fatigue strength characteristics of the automobile stabilizer bar is very important. In this paper, the finite element model is established for the automobile stabilizer bar by utilizing ANSYS finite element analysis software. The automobile stabilizer bar’s strength and stiffness are analyzed with the finite element method. It is ensured that the stabilizer bar meets the static strength requirements. At last, the fatigue simulation analysis is carried out. The simulation results illustrate that the fatigue life of the stabilizer bar is about 673400 times and that it meets the fatigue life requirements which must be at least 500000 times in the fatigue test of the stabilizer bar.
