In order to reveal the vibration characteristics of fault rotor systems caused by the bearing misalignment. the expression of the rotor deflection displacement under the bearing misalignment was derived through the coordinate transformation relation. On this basis. the dynamic model of the double disk rotor system with the coupled bearing misalignment-rub-impact fault. https://www.parisnaturalfoodes.shop/product-category/deep-immune-licorice-free/
