Information
Contact model
The component calculates normal and friction contact forces between disk and housing. The forces are zero until the deflection is larger than the parameter GapShaftHousing.
Figure 1: Contact parameters tab.
The stiffness and damping coefficients for the contact force in the normal direction are kInSurface and damping.
The friction coefficient has a static and a dynamic part. To avoid numerical problems, the friction behavior has been smoothened with the function TripleS_Func.
