Abstract: The transient dynamic response of a flexible rotor in nonlinear supports has been investigated using time marching methods. Several marching techniques such as Newmark β, Wilson θ, and Houbolt ...

Abstract: Response of rotor systems subjected to random support excitations is studied. Support excitations may occur for rotating machines installed either on the ground due to earthquake motion, or on ...

Abstract: A modal reduction technique is discussed and proposed for solving rotor-dynamic problems. The component mode method is used to model a rotor shaft, and the resulting system matrices are reduced ...

Abstract: A new approach is proposed to predict the dynamic behavior of rotor-bearing systems in time domain using the combined methodologies of finite elements and transfer matrices. This approach makes ...
