摘要
x -升降机的两根主轴在正常运转时突然断了。断裂的位置是应力集中较大且弯矩最大的位置。与旋转弯曲疲劳相关的宏观断口特征在断口表面很明显。测得的主轴表面应变随主轴旋转和支撑旋转弯曲疲劳而周期性变化。x升力相对于水平面不是完全对称的。会产生不对称变形，造成主轴弯曲。X-lift的三维有限元分析揭示了主轴的弯曲。
One of the two spindles in the X-lift broke suddenly during normal operation. The location of the breakage is where considerable stress concentration occurs and moreover the bending moment is at the maximum. Macrofractographic features associated with rotating-bending fatigue are evident on the fracture surface. The measured surface strain of the spindle varies cyclically as the spindle rotates and supports the rotating-bending fatigue. The X-lift is not perfectly symmetrical with respect to the horizontal plane. The unsymmetrical deformation can occur and cause the bending of the spindle. The 3-D finite element analysis of the X-lift revealed the bending of the spindle.
