Real-Time Hybrid Testing Techniques

  • Chapter
Modern Testing Techniques for Structural Systems

Part of the book series: CISM International Centre for Mechanical Sciences ((CISM,volume 502))

Abstract

Real-time hybrid testing combines the efficiency of numerical simulation with the realism of experimental analysis. This chapter presents an overview of real-time hybrid test methods from a general perspective, and discusses schemes of structural partitioning and issues related to numerical computation, system dynamics, and system performance. Different approaches of hybrid testing are presented under a unified framework. A specific implementation, including the hardware configuration, numerical integration scheme, and delay compensation methods, is discussed in detail. Results of experimental validation and numerical simulation study are presented to illustrate the effectiveness of several delay compensation schemes and the subtleties of real-time testing. The possibility of conducting reliable real-time hybrid tests using an unconditionally stable implicit integration scheme is demonstrated.

Some of the material presented in this chapter is based on the previous work of the author supported by the US National Science Foundation under the Cooperative Agreement No. 0086592 as part of the Network for Earthquake Engineering Simulation program. The author would also like to acknowledge the important contribution of his former students, Drs. Rae-young Jung and Zhong Wei, to some of the findings presented in this chapter, and the work of Dr. Eric Stauffer in the development of the real-time test system presented here. However, opinions expressed in this chapter are those of the author and do not necessarily represent those of the sponsor.
