Hey all,(adsbygoogle = window.adsbygoogle || []).push({});

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
