Question
Fasten the header cover of the cylinder with an inner diameter of 400 mm and an internal pressure
of 2 MPa with 16 bolts.
1 Additional load applied to one bolt by internal pressure (P)
2 Assuming that the total fastening force per bolt (Qb) is twice the load (P) applied to one additional
bolt by internal pressure, the initial fastening force (Q0) to be applied to the bolt initially
3 Assuming that only tensile force (Qb) is applied to the bolt, the bolt diameter (d1)
4 Considering that tension and torsion act simultaneously, use the empirical formula to find the bolt
outer diameter (d).
Here, the sigma y of the bolt =12
Pa, f(safety factor)=2, Kb=8*10^5N/mm, kg=4*10^6N/mm
