Abstract: In order to evaluate the structural rationality of the stabilizer bar and to optimize its structure, the stabilizer bar of a vehicle was analyzed. The 1/2 finite element model of this type of stabilizer bar is established, the torsional stiffness of the original structure is analyzed, and its stress cloud diagram and dangerous position are obtained. On the basis of the analysis results, aiming at reducing the maximum stress of the stabilizer bar, the structure of the stabilizer bar is optimized without significantly reducing the structural rigidity and increasing the mass. Finite element analysis is carried out for different optimization schemes, and the optimal scheme is determined according to the analysis results. In this study, the dangerous position of the stabilizer bar was determined, and its maximum stress was significantly reduced by optimizing the design. This method can provide guidance for the design scheme evaluation and structural optimization of the automobile stabilizer bar.
