In this paper, an attempt was made to reduce the weight of the intermediate shaft in the automotive steering system by hollowing it. Analysis was performed in order to determine whether the hollow shaft satisfies the requirements for static torsional strength and torsional fatigue endurance. In the static torsional strength analysis, it was confirmed that the maximum stress of the hollow shaft with an inner hole diameter of up to 9 mm was almost the same as the maximum stress of the solid shaft. In the torsional fatigue endurance analysis, it was confirmed that the fatigue life of a hollow shaft with an inner hole diameter of 12 mm also satisfies the requirements. Furthermore, it was confirmed that hollowing the shaft could reduce approximately 20 % of its weight. |
