Title

An Innovative Experimental Approach For Nonlinear Dynamic Physical Simulation Using A Reconfigurable Test Setup

Abstract

The objective of this study is to develop a reconfigurable test setup as an experimental tool to be used in a wide range of nonlinear dynamic studies. The main components include a restoring force generator that can accurately be controlled based upon measured displacement and velocity readings in real-time. The advantage of having such an experimental setup is the ability to simulate various types of nonlinearities with the same test setup. A number of calibration efforts have been made in order to quantify the uncertainty present in the current setup and improve accuracy and reliability of the device. Potential uses for the device are suggested, including the physical deterioration of a large-scale viscous damper. Viscous dampers are critical for mitigating dynamic forces upon civil structures and are heavily utilized in the bridge engineering field. The methodology introduced is very promising as an experimental and cost-cutting tool for researchers and designers. © 2012 Taylor & Francis Group.
