How can I model a train gear in CATIA V5?

By Hotze on 02 Jan 16:53 4 answers 1 comment

I would like to simulate a gear train mechanism with the DMU Kinematics module, but I don't know how. I can build a gear mechanism but only involving two gears. Is there a way to simulate something like gear-a moves gear-b that moves gear-c?
I've solved this problem using a cheap trick in the assembly module: each gear has an angle constaint, so using formulae you can (kind of) simulate the whole mechanism. Anyway, I am sure there are better ways to archieve this.

    there you have gear joint in catia dmu kinematics. you can chose the ratio and leave the rest of the things on the software to work out.

    Send me the model and will do it for you.

    Thanks, Nedim! Here you have a simple model that I personally don't know how to simulate with DMU Kinematics.I hope you be luckier than me.
