Create/Modify Contact Arrays

Contact arrays define the characteristics of force-based contacts. You specify a contact array for each force-based contact. You can, however, use the same contact array with multiple contact forces.
The options for defining the normal force magnitudes for contact arrays are identical to the parameters in the IMPACT function. For information on the IMPACT function, see Adams View Function Builder online help.
 
For the option:
Do the following:
Contact Array Name
Enter the name of the contact array to modify.
Stiffness Force
Enter the force generated for each unit of penetration depth.
Force Exponent
Enter the exponent of the force deformation characteristic.
Damping Maximum
Enter the viscous damping coefficient.
Penetration Depth
Enter the penetration depth at which full damping is applied.
Static Friction Coefficient (µs)
Enter the proportion of normal force applied in the opposite direction of relative motion, from zero velocity to static threshold velocity.
Static Friction Slip Velocity (Vs)
Enter the velocity at which full value of the static friction coefficient is applied.
Dynamic Friction Coefficient (µk)
Enter the proportion of normal force applied in the opposite direction of relative motion, from slip velocity to dynamic transition velocity.
Dynamic Friction Transition Velocity (Vk)
Enter the velocity at which the value of the dynamic friction coefficient has fully transitioned from the static friction coefficient.
