Real-time hybrid simulation in a shaking table

Dec 15, 2015 In addition to hybrid simulation capability that can imitate equipment's interaction with its support structure, the real-time hybrid simulation platform described earlier is a high-performance long-stroke uniaxial shake table. When it is used in a shake table configuration, the test response spectrum envelops the IEEE693 High Performance Level

Response of hybrid isolation system during a shake table

Jun 21, 2018 A full-scale 5-story steel moment frame building was subjected to a series of earthquake excitations using the E-Defense shake table in August, 2011. For one of the test configurations, the building was seismically isolated by a hybrid system of lead-rubber bearings and low friction roller bearings known as cross-linear bearings, and was

Shake Table Testing | Response Dynamics

Shake table testing is often used in prototype analysis, failure analysis, shipping vibration testing and vibration sensitivity testing. We know what boundary conditions are vital for effective testing, how and where to instrument the system, how to deal with off-axis excitation (often not accounted for), and make the most efficient use of testing time

Frontiers | Advances in Real-Time Hybrid Testing

Aug 07, 2020 The control strategy of shaking tables, such as the tri-variable control method, is quite different from the control method of a single actuator often used in real-time hybrid test, further hindering the development of STST. The knowledge accumulated from real-time hybrid test may not be directly applicable in STST
