How to model gear-pinion-rack system in OpenSees?

Post by Shubhang » Mon Jun 21, 2021 6:22 pm

I wanted to amplify the deflection at a node by using the gear-pinion-rack system in OpenSees. Are there any inbuilt commands that I can use to model it? Please suggest some ideas.

Thanks.

There is no built-in command. You can try modeling it with translation and rotation springs.

Dear Sir. Can you briefly write, how exactly i can use rotational spring to model the gear of some diameter?
