摘　　要：以含裂纹提升机主轴为研究对象,利用ABAQUS的子模型技术,模拟计算了不同工况下提升机主轴三维表面裂纹附近的应力应变场,获取了J积分在承受复杂载荷的主轴椭圆裂纹扩展过程中的变化规律。研究结果表明,椭圆裂纹中点和两端的扩展明显要慢于裂纹其他部位,并为轴类零件结构完整性评价提供了一定的理论依据。The stress and strain fields ahead of three-dimensional surface crack in an elevator shaft is simulated and studied by using ABAQUS sub-model technique in this paper. And it is adopted that the distribution of J-integral along the semi-elliptical crack front in the elevator shaft under complex loading conditions. The results of this investigation show that the elliptical crack propagation at the midpoint and both ends is significantly slower than that of other parts of the crack front, which provides a theoretical ＇basis to evaluate the structural integrity of shafts.
