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.
