Good morning to all,
Recently I'm dealing with axioms that predict the use of bolted joints for links, which I have to simulate with ansys workbench (this is my magistrate thesis project). premitting that I have just some notion regarding bolted joints (the rest I am learning it now), I have obtained through the tables found on the legislation the value of the preload to be applied, known the diameter of the bolt, the class of resistance and friction coefficient; that value obtained should represent the max value of procarious applied (for a greater the risk of the yielding of the bolt), that, from the simulations made in ansys riulta according to me a little excessive for my application, as the connected plates clearly are tightened and do not move, but the tensions that I find on one of the plates are a little too high and depend strongly on the applied precarious.
now a solution would be to reduce precariousness progressively and do various analyses until you find a fair compromise between the functionality of bolting and stress resulting from its applucation. the question that I ask myself and if there is any criterion that, according to the application, i.e. the number of used bolts and material of the connected plates, allows to define the right value of the preload.
I hope I've been properly explained.
Thank you in advance.
