Relative rotation system is a widespread power transmission system, which contains many nonlinear factors such as the nonlinear damping, stiffness, and backlash.
In the study on vibration measurement techniques on TCS, it is also found that damping parameters will change with the external excitation levels, and if the thickness of hard coating is larger, then the nonlinear damping influence would be more obvious.
Let us consider the long-time behavior for the following Kirchhoff plate equations with fading memory and nonlinear damping:
where [mu] is the scalar parameter indicating the strength of the nonlinear damping, and (12) is called the Van der Pol equation in the autonomous regime.
The relationship between the nonlinear damping [C.sub.z[beta]] and [C.sub.s] is
The joint shaft has been considered to embody torsional stiffness [k.sub.n-1], nonlinear stiffness [K.sub.NL], linear damping [c.sub.n-1], and nonlinear damping CNL.
