| Abstract | Driveshafts are used to transmit the driving force in automobiles. The required shaft strength is ensured by applying heat treatment to the internal parts. This paper presents a method to improve the accuracy of strength predictions for driveshafts by incorporating the effects of heat treatment on the distributions of hardness, strain, and residual stress into strength analysis. By comparing strain amounts between analysis and actual measurements, it was confirmed that this novel method can predict the actual measurements better than conventional methods, and therefore improve the accuracy of strength predictions. |
