Comparison of real time hybrid testing of magnetorheological damper with pure numerical and physical systems

Real-time hybrid testing is a method frequency utilized for assessing systems with nonlinear and challenging-to-model elements. This approach integrates numerical and physical components, allowing for swift and cost-effective refinement of system iterations. In this research, a magnetorheological (MR) damper is used as the physical substructure due to its inherent nonlinear, hysteretic behavior, while a simple four-story structure serves as the numerical substructure. The effectiveness of the proposed real-time hybrid testing framework is validated by comparing its results with both analytical and physical recreations of the experimental system. This comparison aims to confirm the framework's reliability and its potential as a testing method for systems with complex, nonlinear components.
