Forces on bolt during vibration
Hi
I am trying to do an analysis on what is the minimum size of bolts I would need to use on an electrical enclosure that is to be wall mounted. This whole unit would be mounted on the inside of a vehicle subjected to vibrations. I have attached a pdf to explain.
The enclosure is composed of 2 halves (front panel and chassis). At a state of rest, the axial load on the bolts would be purely due to the preload after tightening. The shear force would be solely due to the weight of the panel.
During vibration, I assume that these forces would be magnified. How do I calculate the effective forces?
