Real-time Hybrid Simulation Benchmark Study with a Large-Scale MR Damper
Real-time hybrid simulation is a powerful and cost effective alternative for testing rate dependent structural components such as advanced energy dissipation devices. Hybrid simulation, of which real-time hybrid simulation is a subset, combines numerical simulation with experimental testing in a closed-loop framework. Real-time hybrid simulation frameworks are not yet standardized. Indeed, most are built using different hardware and software, including different numerical integration and delay compensation techniques, leading to potentially different system behavior for setups designed to test the same structure. A simple three-degree-of-freedom structure with a magnetorheological (MR) damper between the ground and first story is proposed for a real-time hybrid simulation benchmark study. This study is aimed to help corroborate real-time hybrid simulation frameworks, develop MR damper models under semi-active conditions, and develop semi-active control strategies, all in a simple yet realistic environment.
