What is the nonlinear state space model (nonlinear model) of rotary flexible link

Since the rotary flexible link is a nonlinear system, what is the nonlieanr state space model (nonlinear model) for the rotary flexible link, before linearizing it?

I know the linear state space model, but my question: what is the nonlinear equation (nonlinear state space model) for the rotary flexible link?
