How to calculate the unit load on the horizontal container cylinder?
Thread Content
As shown in the figure, in Chapter 7.7 Strength Calculation of Horizontal Vessels of NB/T 47042-2014 "Horizontal Vessels", in the calculation of the maximum axial bending moment of the cylinder, the bearing reaction force on the unit length load saddle on the cylinder is F/2, but the corresponding bearing reaction force on the cylinder is q=2F(L+4h/3) Why is the unit load not in the form of force/distance, but in the form of force × distance? How is the unit load q=2F(L+4h/3) of this part calculated? Please give me some advice from the great god of materials mechanics! ! !
It should be 2F/(L+4h/3)
I discovered it too! ! Can you explain how the force of the head on the cylinder part q×2h/3 is calculated? How did the center of gravity of the head end come to be 3h/8?
2/3h is the rule, and this is also the case when calculating the length of 150 negative pressure.
It turns out that there are already provisions and instructions in HG/T 20582-2011 "Regulations on Strength Calculation of Steel Chemical Containers"! ! !
Oh, it's converted into the equivalent of a cylinder. I misunderstood it, and thought it was the surface depth calculated by negative pressure. The surface depth calculated for negative pressure is 1/3h, here it is 2/3h.
