Non-Linear Friction Model

  1. May 29, 2009 #1
    Hey all, I'm cross-posting this in the materials and mechanical engineering section because I feel like this might be a good question for both places.

    I'm trying to develop a physical model of a mechanical system in MapleSim, and have the questions about the friction model used. This isn't a software question, but more trying to understand the math of a non-linear friction model.
    The model itself is a sum of the Coulomb friction (the familiar F= uN component), as well as Stribeck and viscous effects.
    As a result, the model requires input parameters such as breakaway friction force, viscous friction coeff., and transition approx. coeff.
    My question is: How can I get numbers for these values? I have some performance data for my system but what do I need to know to find numbers for those input parameters? Can they only be determined experimentally?

    Thanks in advance,
    -Max
