The Spinning Friction contact model is used to account for the friction that would occur if a particle face is rotating against another particle or Geometry.

The most basic friction model is the Coulomb model [20] where the force of friction is given by Fc = „Fn sign(v) (1.1) where Fn is the normal force, „ the friction coefficient and v the relative …

Modeling Methods • State assumptions and their rationales • Establish inertial coordinate system • Identify and isolate discrete system elements (springs, dampers, masses) • Determine the …

This short expose of some friction mechanisms illustrate the difficulty in modeling friction. There are many different mechanisms. To construct a general friction model from physical first …

This equation models the basic physics of a spring — it describes how a spring exerts a force when you push or pull on it. The force (F) (in newtons) is proportional to the displacement (x) …

The well-known linear elastic spring will be reviewed to illustrate the concept of obtaining equilibrium equations from an energy formulation. Consider a linear spring, of stiffness k, and …

An ideal linear spring has no mass and a linear relationship between force and elongation. For viscous friction there is a linear relationship between force and velocity. Friction may either be …

A model of a system that connects rotational and translational motion. A summing lever drives a load consisting of a mass, viscous friction, and a spring connected to its joint C. Joint B is …

Select Edit Contact Chain > Base Model and then select Linear Spring. Select the required rolling friction or additional models. Click the configuration icon to define the contact model parameters.
