Abstract: A new approach to the dynamic characteristic of undamped rotor-bearing systems is presented. The dynamic behavior of a rotor bearing system is usually studied using finite element approach and/or ...

Abstract: The Generalized Polynomial Expansion Method (GPEM) is utilized to model a large-order flexible-rotor system with nonlinear supports. With the application of GPEM, a set of nonlinear ordinary ...

Abstract: The objective of the present study is to develop an efficient design algorithm for minimum weight design of a rotor bearing system under the requirements of operational speed range, i.e., ...

Abstract: An efficient design algorithm for optimum weight design of a rotor bearing system with dynamic behavior constraints is investigated. The constraints include restrictions on stresses, unbalance ...
