Optimization of a Certein Torsion Beam Suspension Based on Sensitivity Analysis

Zhang Peng;Wang Hao;Chen Liqing;Anhui Agricultural University;Anhui Jianghuai Automobile Co.,Ltd.;  
According to the principles of mechanics of materials,based on the spatial coordinate transformation matrix and analytic geometry of space,the shear center of a certain torsion beam suspension was established and calculated.The model was aimed to get the kinematical equation and modify the structural parameters.By using partial derivative methods,the sensitivity formula of suspension structural parameters to the kinematics property were worked out.Based on the sensitivity formula,the most influences parameters on the kinematics property would easily get,by modifying these factors,the kinematics property of this suspension would become better.A finite element model was established to show the calculation way of the shear center was reliable.ADAMS model and test results show that the analysis method is right.
