| Abstract: | By utilizing the size and shape optimization method of OptiStruct,the thickness of the cross car beam and the shape of the tubular beam are optimized to ensure the performance of the first order vertical modal and the first order lateral modal,while maximizing the weight reduction.The results show that the weight reduction of cross car beam is 1.445 kg,and the reduction percentage is 19.3%. |
