Kinetic friction#
Name#
Define the name of the link property.
Physics type#
Shows if the link property is mechanical or thermal.
Property type#
Shows the link property type.
Friction force and torque#
Define the direction of the friction force. The friction force should be applied in opposite direction of the movement.
Build-up velocity#
Define the velocity at which 96% of the friction force is built up.
Friction model#
The friction force is calculated according to the following equation:
\[f = f_v * tanh(2/v_b*v)\]

Linearize#
The non-linear effect of the kinetic friction can be omitted in the analyses by ticking the linearize link properties box. Check the user help for analyses for further information on linearization.
