- •
A novel hysteretic force model is proposed to describe the contact force of the rotor blade and casing.
- •
For the rub-impact with hard and soft coatings, the hysteretic contact force model can be simplified to the Kelvin–Voigt model and Lankarani–Nikravesh model, respectively.
- •
Impact experiments are performed on the rotor test rig to estimate the values of model parameters and ensure the validity.
