is there any possibility to consider the surface roughness in the calculations? I am trying to validate a conic press fit, where the surface roughness plays an important role in calculating the oversize. Probabily because of the missing roughness I get much bigger forces and deviations with PrePoMax than with hand calculations.
Surface roughness is usually modeled by generating random or structured surface deformations or applying them from point clouds from 3D scans. The result is something like this:
Yeah, I would also choose a simplified analytical approach in such a case. Surface roughness modeling is not needed in most cases apart from research purposes.
Coulomb friction coefficient tested and provide different type of material including stone and steel, so my understanding in roughness are directly correlated.
