As each other, the "fear factor," which is conventionally equal to the number of children + 1. Let's assume we have a direct connection with a battery of PSV 6×10′ valves. The thrust force per additional catalog is 33 kN.
DLF determined in accordance with the harmonized standard is 2.0. It can be seen that for PSV valves, which generally operate very quickly, DFL = 2.0 can be used by default.
At this point, the x DLF force can be used in static analysis, but also in dynamic analysis. Static analysis is quite straightforward, so I turned to dynamics.
First, I generate a flat spectral DLF = 2 with the valve opening time calculated above of 1.304 ms.
I add the thrust force from the manufacturer's data sheet and then the load combination.
The results are interesting.
