应力集中点 meaning in English
focal point of stress
hard spot
stress concentration point
Examples
- The emphases has been put on calculation of the points with concentrate stress . meantime , according to the situation of surface and non - line relation between stree and strain , it modificates the method
本文还介绍了应力的计算方法，重点考察了联箱应力集中点的应力值，并且根据表面状况，以及应力和应变非线性关系对应力进行了修正。 - For pump shafts , the results reveal that the stress in the spline is higher than the other parts of the shaft , and the highest stress is at bottom and terminal of the spline . in fact , the broken of shafts is at the same position ; it demonstrates that the calculation is right
实践证明，轴断部位基本集中在潜油泵轴花键的根部，说明计算结果和实际是吻合的；对于潜油电机轴，应力集中点主要处在轴承键与环槽的交界处和花键的根部。 - To meet the demand for the high intensity belts , the paper is to design the drum whose diameter is above 1600 millimeter . then modeling , carving up the net , analyzing the stress with the finite element method and finding the focus points of the stress and rebuilding the structure , so that we can design a reasonable drum under the force
本课题主要是为适应高强度皮带的要求，对直径为1600mm以上的大型带式输送机滚筒进行设计，然后用ansys软件建模，进行网格划分，对其所受的应力进行有限元分析，找到应力集中点并对其结构进行改造，设计出受力合理的滚筒。 - 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
其中对17 . 4mm泵轴的优化，通过增大花键内径，提高了花键齿底的强度，降低了应力集中点附近的应力；对30 . 2mm电机轴的优化，通过在轴承键的环槽端增加倒角，有效降低了该位置的应力集中，使轴的最大应力点从轴承键与环槽的交界处转变到花键根部与收尾的交界处，提高了电机轴整体结构强度的合理性。
