Calculation of local stress at axial lifting lug
The calculation of the local stress of the cylinder at the axial lifting lug was not intended to be written. But I found that there are still many people who don't quite understand that there are such problems in the input, and the input results are only too much or too little according to the software prompts; In addition, the thickness of the cylinder at the shaft lug recommended by HG/T 21574 is also too thick, which is still required by many people. Just say:
If there is no lifting process calculation, the horizontal and vertical state of the equipment will be considered. If there is a lifting process, the load at each angle shall be calculated at the angle of the maximum value. In theory, the local stress of the cylinder at the axial lifting lug is the largest when the equipment is horizontally lifted, and the axial lifting lug itself is the most dangerous when the equipment is vertical. This paper does not discuss the calculation of the shaft lifting lug body, but only the input and result judgment of the local stress calculation of the cylinder at the shaft lifting lug.
