  3. For the 30. 2mm shaft, there are still larger over measure to load. the strength is increased by optimization. for ? 17. 4mm shaft, the strength is increased by enlarge the inner dimension of the spline ; for 30. 2mm shaft, the strength is increased by adjust the structure at the boundary between the key groove and the ring groove, the highest stress of the shaft is at bottom and terminal of the spline after optimization

    其中對17 . 4mm泵軸的優化，通過增大花鍵內徑，提高了花鍵齒底的強度，降低了應力集中點附近的應力；對30 . 2mm電機軸的優化，通過在軸承鍵的環槽端增加倒角，有效降低了該位置的應力集中，使軸的最大應力點從軸承鍵與環槽的交界處轉變到花鍵根部與收尾的交界處，提高了電機軸整體結構強度的合理性。
