N2 - The conventional friction force model is used in many kinds of contact algorithms. The friction coefficient of the conventional friction force model is only a function of relative velocity. When you simulate a simple contact model, in which a body is on a sloped surface, if the friction coefficient between the body and sloped surface is less than the static friction coefficient, the body should be stuck. But in the case of conventional friction force model, the body will be sliding because the relative velocity must have a non-zero value in order to generate the friction force. In order to solve this kind of problem, the stick-slip friction force models have been developed by many researchers. In the case of stick-slip friction force model, the body can be stuck on the sloped surface because the friction force will be a non-zero value, even though the relative velocity approaches zero. In this paper, the stick-slip friction model is applied in the contact algorithm of multi-body dynamics (MBD) systems and two friction models are compared. From the applied stick-slip friction model, we can get more realistic results and improved solving speed. Copyright (c) 2010 by JSME.
