Friction (Cam-Follower)
By adding a Friction subnode to a Cam-Follower node, you can model frictional forces and losses between the cam and the follower. There can only be one Friction subnode under a Cam-Follower node.
Friction
Enter a Friction coefficient μ.
Enter a Characteristic slip velocity v0. The default is mbd.diag*(1e-3[1/s]), where mbd.diag is the diagonal of the geometry’s bounding box. The characteristic slip velocity should be small compared to the actual slip velocity at the contact point. This is the velocity with which the contact surfaces slide, even under sticking conditions.
Advanced
Enter values or expressions for the:
Maximum friction force Ff,max. The default is Inf, which means that no upper limit is imposed on the friction force.
Select Compute frictional dissipation to compute and store the energy dissipated by friction. This adds a global dependent variable with an ODE in order to integrate the dissipated energy.
