Optimal Design Support System for Rotor Dynamics Based on the Experimental Design Methodology

Abstract

To improve efficiency and reduce costs, it is necessary to reduce the number of steps is the rotor development process. This can be achieved by combining the use of CAE and computer-aided optimization (CAO). To meet the increasing demand for CAO in the rotor dynamics design field, we developed a rotor dynamics design support system. This system provides a FEM-based rotor dynamics analysis function, and the design of the experiment is based on a CAO function. In this paper we will explain the CAO function, as well as provide a case study on second bending vibration mode optimization, which is generated by an imbalance in a damper bearing supported model rotor.
