Optimal Rotor-Dynamic Design Based on Experimental Design Methodology. Optimal Design Methodology for Rotor Systems Supported by Damper Bearings.

Abstract

When designing rotor systems, development costs and the number of trial production runs must be minimised. To do so, the optimum structure must be found by combining CAE optimisation tools during the initial stages of development. We propose a low-response magnification design method for process compressor rotor systems supported by damper bearings. The effectiveness of this method is demonstrated by experiment. The main elements of our system are (1) a variance analysis of the contribution rate of design variables and mutual actions, (2) an assignment of the design variables to the orthogonal array, (3) a rational parameter survey of this array, and (4) an understanding of solution space from multiple points of view gained by using an approximation method for a response surface model.
