How to have a car follow a track in kinematics?


New member
Hello! I'm trying to simulate a new type of roller coaster in CATIA with the DMU Kinematics workbench. Currently, I can do any hills in a straight line perfectly fine, but I can't seem to get it to go around a horizontal curve. I have deactivated the upper chasis as seen in the video in order to just get the lower chasis to follow the curve. I have 8 roll curve joints between the 8 road wheels and the wire frame sketch on top of the rails. Any idea on why the car won't negotiate the turn? It gets to the point pictured above and then stops. Is there a better way to have the car follow the track other than using a ton of roll curve joints?
