开槽轴的扭转应力浙江机械工业学校何西泠在轴上沿轴线方向开圆形槽，这在工程实际中是常见的。当轴传递扭矩时，开槽处出现局部“应力集中”，在“应力集中”区内可能发生疲劳破坏。因此，在开槽轴的设计中，应当考虑轴的有效应力。一根半径为ａ的圆截面轴，开有半径为ｂ... Torsion stress of slotted shaft Zhejiang Mechanical Industrial School He Xiling opens a circular groove along the axial direction on the shaft, which is common in engineering practice. When the shaft transmits torque, local “stress concentration” occurs at the slot, and fatigue damage may occur in the “stress concentration” zone. Therefore, the effective shaft stress should be considered in the design of slotted shafts. A radius of a circular cross-section axis, open a radius of b ...
