| Abstract: | Based on a original design for the torsion bar spring, using the process of DFSS, the CAE finite element model was set up, the factors which affected the torsion bar spring＇ s function were analyzed comprehensively, eighteen alternative design schemes were proposed, and then the best design scheme was found out from all. Both the simulation results and the road test results prove the optimized design scheme not only eliminates the risk of crack, but also improves the torsion bar spring＇ s life time more than 5% , declines 10% weight. Moreover, it proves the DFSS＇ s usefulness in the field of vehicle parts quality improvement. |
