Where to specify Damping values ?

draucis

Hello,

This might be a very basic question but please bear with me, I am relatively new to all this, and I appreciate everyone who is helping me out.

So, I am confused about how to specify damper values in motion view. For Dampers there are like 3 places where we can specify it's value.                                                                                                                                                                                                                        1.) the spring parameters in the model browser - C value

2.) the damper curve under shock damper property

3.) the damper value on its own in shock damper property and that also has a k value.

in the shock damper property, we can switch between how we want to give the value for dampers, like in a curve, expression or something else.

Out of the three positions mentioned where should I consider specifying the value.

Also, what does jounce and rebound bumpers represent in an actual shock. While assembling the model there is an option to add this and also not.

Hey Praful,

Yes, you can take the Electric sports bike as an exmple it also has the same things which i am talking about.

I have attached snap shots of what I am talking about.

Hello Draucis

The SpringDamper entity as such is a combination of spring and damper.The damping can be provided in the same one single entity.

But in the Mono shock system, the spring and the damper have been separated by creating 2 separate spring-damper entities. One for the spring (whose damping value has been set to 0.0) and other for the damper (whose spring stiffness has been set to 0.0).

You may define the damping however you wish. In the Spring (there by deactivating and deleting the Shock damper) or in the Shock damper. By having them separate it becomes convenient to have separate outputs so that the force caused by the spring action and damping action can be measured separately.

The Shock damper has been set to use a Curve (Damper Curve), thereby the damping can be defined as a non-linear Force v/s Velocity curve. If you want to represent a linear damping, you may shift the property to Linear and provide a damping coefficient. If you wish to retain non-linearity you may want to modify the damping curve.
