shaft of radius

The computation results show that there exists serious stress concentration on the fractured section of the shaft. The main reasons of high frequency fatigue fracture of the shaft are that the small transition radius and the tensile stress caused by the tightening torque of the bolt.

结果表明，花键轴断裂处存在严重的应力集中，花键轴断裂处过渡圆弧半径过小以及未对螺栓拧紧力进行控制是导致轴产生高周疲劳破坏的主要原因。
