  • According to the characteristics of double-wishbone suspension with torsion bar, establish a simulation model of a car independent suspension was established by multi-body dynamics theory. According to the formal structure of torsion bar spring, loads of key points at three typical load conditions in ADAMS/Car were drawn and turned into torsion as the loading condition for statics analysis;statics analysis of the torsion bar was taken in typical conditions with ANSYS. The structure of hollow rod was designed; Three best programs were gotten by taking single objective global optimization on torus torsion spring bar which based on the response surface method.Comparison of the results after optimization and original showed:the mechanical properties of torsion bar improved significantly after optimization, the maximum equivalent stress decreased by 24%, the total deformation decreased by 31%, and the quality of torsion bar decreased by 11%.
