Response Surface Methodology based Multi-Objective Optimization of Stock Bridge Damper for Pump Induced Floor Vibration

Abstract

To attenuate the vibration induced by pump on a steel floor, an investigation has been done following Weighted Desirability Function (WDF) and Response Surface Methodology (RSM) coupled central composite design and Weighted Desirability Function (WDF). The main purpose of this paper was to formulate a Weighted Multi-Objective Optimization (WMO) of Stockbridge Damper parameters. Mass ratio and frequency ratio were considered as design variable to optimize the parameters of damper. The objective functions were the frequency response and the top displacement. The optimization has been carried out under pump which can generate different frequency with different RPM (0–3000). The optimal Stockbridge Damper depending on RSM indicates improved response among different cases. The proposed response model shows an efficacious approach regarding Stockbridge Damper optimization.
