How create a constraint network for simulating Car Suspensions in Houdini?

#1

Hi Guys,

I’m trying to create a constraint network for simulating Car Suspensions, but with no results. I just need a simple “spring effect” between Body and Wheels (please find a video example attached or visit here https://www.youtube.com/watch?v=uNXaM3OYRCc sec 00:08). How can I do it?Any suggestion will be really appreciated. Thank you! :slight_smile:

there are multiple ways:

when you want a quick and simple way (low quality):

simulation based (high quality):

there are also tutorials for car simualtions but they are a bit old:

you also can check the collitions tutorials from jeff (1 to 3):

Hey Mandranke0, thank you for your reply. I already tried with Spring and RBD Spring Constraint, but it doesn’t work. I need to understand how to create with simple Hard and Spring Constraint Relationship.
