The objective of this numerical study is to investigate the effect of aluminium material on the weight reduction in tubular shaft yoke and solid shaft yoke. The tubular shaft and the solid shaft were designed by 6 stage processes and the results were analyzed by using a finite element analysis method. The coefficient of friction was set to Oil_cold as referred to the analysis library. It was found that the weight was reduced as 65% with applying the aluminium alloy due to lower density than carbon steel. Von-mises stress values of applying aluminium alloy to the tubular shaft yoke and solid shaft yoke were lower than those of carbon steel because of the low yield stress of aluminium alloy. The folding and underfill phenomenon were not observed on the aluminium alloy in tubular shaft yoke and solid shaft yoke. From these results, the weight reduction of products and the extend life of dies can be expected when aluminium alloy is applied.
