Modify a Spring-Damper Force

Right-click spring damper → Modify
For a Translational spring damper, you can modify:
■Parts between which the spring damper acts.
■Stiffness and damping values, including specifying splines that defines the relationship of stiffness to displacement and damping to velocity. Learn about defining Splines.
■Preload values.
Learn about:
For the option:
Do the following:
Name
Enter the name of the spring damper to modify.
Action Body
Change the action body to which the force is applied.
Reaction Body
Change the body that receives the reaction forces.
Stiffness and Damping:
Stiffness Coefficient/
No Stiffness/
Spline: F=f(defo)
Select one of the following:
■Stiffness Coefficient and enter a stiffness value for the spring damper.
■No Stiffness to turn off all spring forces and create a pure damper.
■Spline: F=f(defo) and enter a spline that defines the relationship of force to deformation.
Damping Coefficient/
No Damping/
Spline: F=f(velo)
Select one of the following:
■Damping Coefficient and enter a viscous damping value for the spring damper.
■No Damping to turn off all damping forces and create a pure spring.
■Spline: F=f(velo) and enter a spline that defines the relationship of force to velocity.
Length and Preload:
Preload
Enter the preload force for the spring damper. Preload force is the force of the spring damper in its reference position.
Default Length/
Length at Preload
Select either:
■Default Length to automatically use the length of the spring damper when you created it as its reference length.
■Length at Preload and enter the reference length of the spring at its preload position.
Tip: If you set preload to zero, then displacement at preload is the same as the spring’s free length. If the preload value is non-zero, then the displacement at preload is not the same as the spring’s free length.
Spring Graphic
Specify whether coil spring graphics are always on, always off, or on whenever you have defined a spring coefficient.

modify: Click to modify the Spring Graphic values.
Damper Graphic
Specify whether cylinder damper graphics are always on, always off, or on whenever you have defined a damping coefficient.

modify: Click to modify the Damper Graphic values.
Force Display
Specify whether you want to display force graphics for one of the parts, both, or none. By default, Adams View displays the force graphic on the action body.
