Click Damper (MotionManager toolbar).

Damper Type

 Linear Damper (Motion Analysis only). Represents forces acting between two parts over a distance and along a particular direction. You can specify the location of the damper on two parts. The Motion Analysis study: Calculates the damping forces based on the relative velocity between the locations on the two parts Applies the action force to the first part you select, the action body. Applies an equal and opposite reaction force along the line of sight of the second part you select, the reaction body. Torsional Damper (Motion Analysis only). Rotational damper applied between two components about a specific axis. The Motion Analysis study: Calculates the spring moments based on the angular velocity between the two parts about the specified axis Applies an action moment about the specified axis to the first part you select Applies an equal and opposite reaction moment to the second part you select

Damper Parameters

 Linear dampers selection box Lists the pair of features defining the damper endpoints. Torsional dampers first selection box Lists the feature defining one end of the damper and the torque direction. Select a second feature only to change the torque direction. Torsional dampers second selection box Lists an optional second feature that defines the damper. Leave this selection empty to attach the damper to ground. Exponent of Damper Force Expression Based on the Functional Expressions for Dampers. Damping Constant Based on the Functional Expressions for Dampers.

• Linear damper: `- c*v**n`
• Torsional damper: `- ct*omega**n`
 `v` is the current relative velocity between parts at the attachment points. `omega` is the current angular velocity between the parts, about the user-defined axis. `c` is the Linear Damping Constant. `ct` is the Torsional Damping Constant. `n` is the Exponent. For example, if the spring force = `-kx2`, then `n = 2`. Valid options are `<-4,-3,-2,-1,1,2,3,4>`.
