Hi Experts,
Basically I am running a assembly simulation with 4 components
by using SW/Simulation Static. I have several contact sets beside
global contact. I have set the friction coefficient to be 0.35 for all contact sets because it is steel/steel contact with lubrication. System is fully constrainted and simulation is running smooth.
Problem is when I use "list reaction/contact..." in the result
folder to take a closer look at those contact sets. I found for
two contact sets the ratio between friction force and normal force
to be 0.04X and 0.09X, respectively. Why? Shouldn't they to be roughly 0.35? It is a big deal for us, because a part supposed to be self-locking but it is not right now because of lower friction coefficient. Thanks a lot in advance for everyone's comment.
I am using 2011 Solidworks with simulation premium (highest level). Again it is a static study, the most basic one.
