Abstract: Lightweight is an important technological breakthrough direction for commercial vehicles. The reduction of curb weight can achieve the goal of energy saving and emission reduction. In this paper, based on the new technology and test method of automobile lightweight, using the finite element software Hyperworks, the structural optimization and comparative analysis of a light truck foundation steel transmission shaft and aluminum alloy transmission shaft lightweight scheme are carried out. At the same time, the parts bench test equipment is built, the max torsion capacity of aluminum alloy transmission shaft is studied, and the vehicle noise,vibration and harshness test analysis is carried out, the CAE analysis of the aluminum transmission shaft lightweight scheme is equivalent to that of the base steel scheme, and the noise,vibration and harshness real vehicle performance of the aluminum alloy transmission shaft scheme is better than the base shaft, and the weight of aluminum transmission shaft is reduced by 12 kg, and the lightweight effect is remarkable.
