Title:
VEHICLE/BRIDGE VIBRATION MITIGATION ASSEMBLY
Document Type and Number:
WIPO Patent Application WO2000009349
Kind Code:
A3
Abstract:
A vibration mitigation assembly (10) for mitigating vibration of a bridge (14) as a vehicle (12) travels across the bridge (14) is provided. The vibration mitigation assembly includes a plurality of adjustable actuator assemblies (18) having a first fluid chamber (54) and a second fluid chamber (56) interconnected by a valve (42). The actuator assemblies (18) being connected to the vehicle (12) and motion sensors (26-31) being attached to the vehicle to measure vibration of the vehicle (12). In response to the motion data, a controller (24) outputs a control signal to the valve (42) to vary the flow rate of the fluid between the first and second chambers (54, 56) such that the amount of vibration energy dissipated by the vibration mitigation assembly (10) is selectively varied whereby both a stiffness of the adjustable actuator assemblies (18) and the amount of damping are continuously adjusted to prevent resonant coupling between the vehicle (12) and the bridge (14) over which the vehicle is traveling.
