Mass-spring System

Hello,

I am trying to create a simple spring mass system. Therefore I'm using a baseplate, which I fix to the origin, a spring damper part and a mass on top. It's basically like in the sketch I added, just upside down.

I am able to fix the baseplate and the spring to the baseplate. But if I try to animate the whole model, the mass just falls off. I used a translational joint to fix the mass to the spring.

 

Thank you for your help!

    Hi Blumi

     

    have you fixed the baseplate to ground body?

    Blumi,

     

    Actually you can skip the base plate, you can directly attach the spring to ground body.

     

    While creating Spring damper, select either body 1 or body 2 as Ground body
