    How to define surface roughness for motion simulation

    Valerie Pfening

      Hi all,


      my question is how to define the surface roughness. I have a cylinder liner where a piston (with piston rings) is moving up and down.

      Cylinder liners have a honed surface (Ra 4 - 8 µm). I have three different honing types and I want to identify the friction force with the motion simulation.

      I really do not know how to define the roughness of the surface.
