Vehicle/bridge vibration mitigation assembly |
摘要 |
A vibration mitigation assembly for mitigating vibration of a bridge as a vehicle travels across the bridge is provided. The vibration mitigation assembly includes a plurality of adjustable actuator assemblies having a first fluid chamber and a second fluid chamber interconnected by a valve. The actuator assemblies being connected to the vehicle and motion sensors being attached to the vehicle to measure vibration of the vehicle. In response to the motion data, a controller outputs a control signal to the valve to vary the flow rate of the fluid between the first and second chambers such that the amount of vibration energy dissipated by the vibration mitigation assembly is selectively varied whereby both a stiffness of the adjustable actuator assemblies and the amount of damping are continuously adjusted to prevent resonant coupling between the vehicle and the bridge over which the vehicle is traveling.
