Hi, I am working on a drop test simulation of a landing gear. So, i’ve been using the penalty method for the physical contact (with friction) but i have a small problem while figuring out the coulomb coefficient.
What i’ve understood about this coefficient is that it is independent on the tangential sliding velocity (between the main body and base) of the geometry and is slightly different from the normal coefficient of friction.
I wanted to know; what can be done to estimate this parameter ?
Also on what more parameters is this coefficient dependent upon ?
Here is my project (look at the latest simulation):
