Stick-slip algorithm in a tangential contact force model for multi-body system dynamics

Abstract: Contact force of Multi-body dynamics (MBD) system can be classified two parts. First is a normal force and the other is a tangential force called friction force. And the friction force can be represented by two states such as stick and slip. The stick-slip phenomenon is simply described as a simple contact model which is a rigid body contacted on a sloped surface. If the calculated friction coefficient between the body and sloped surface is less than the static friction coefficient, the body should be stuck. I… Show more

“…With the continuous application of virtual simulation technology in the study of the creeping phenomenon, different types of friction models [15][16][17][18] have been established and verified by the simulation. A two-degree-of-freedom mathematical model [19] was used in an earlier study to simulate the stick-slip motion of the guide moving and agreed with the experimental results.…”

“…Then, the friction force is calculated by the normal contact force and the relative velocity as equation (2): where F f , μ , υ and F n are the contact friction force, friction coefficient, relative velocity and contact normal force, respectively. The sign and magnitude of the friction coefficient can be determined from the relative velocity of the pair on contact position (Cha et al , 2011). The relative position and orientation of the action body to the base body are defined as the generalized coordinates, which are denoted by u a and A a .…”
