Design Approach and Practical Formulas of Electromagnetic Inertial Mass Dampers for Cable Multimode Control
Publisher: ASCE
Abstract: An inerter-based damper termed electromagnetic inertial mass damper (EIMD) has been demonstrated as a high-performance passive damper for bridge stay cables. However, how to design an EIMD for suppressing cable multimode ...
Identification of Frequencies and Track Irregularities of Railway Bridges Using Vehicle Responses: A Recursive Bayesian Kalman Filter Algorithm
Publisher: ASCE
Abstract: On-board monitoring of track irregularities and bridge dynamic characteristics based on vehicle vibration responses provides basic data for the condition assessment of high speed railway bridges. However, the identification ...
Unify Energy Harvesting and Vibration Control Functions in Randomly Excited Structures with Electromagnetic Devices
Publisher: American Society of Civil Engineers
Abstract: With the extensive studies on energy harvesting via electromagnetic devices in civil or mechanical structures, a novel dual-function device, termed electromagnetic damping and energy harvesting (EMDEH) device, has been ...
Design Formulas of Electromagnetic Inertial Mass Dampers for Cable Vibration Mitigation
Publisher: ASCE
Abstract: This study proposes the design formulas of an inerter-based damper termed electromagnetic inertial mass damper (EIMD) for bridge stay cables. To maximize the modal damping ratio for a specific cable vibration mode, we ...
Track Irregularity Monitoring on High-Speed Railway Viaducts: A Novel Algorithm with Unknown Input Condensation
Publisher: ASCE
Abstract: The inverse dynamic analysis of vehicle-bridge (VB) systems provides a superior scheme for track irregularity identification using the onboard measurement data of vehicle dynamic responses. However, available algorithms ...
