Abstract

The invention discloses a road bridge supporting device for reducing the influence of resonance. The road bridge supporting device comprises a pier, anti-interference mechanisms for reducing the influence of vibration of a bridge deck, buffer blocks for installing bridge modules and a one-way passage mechanism; the anti-interference mechanisms each comprises a special-shaped tube, a lifting sealing plate for pushing generated air flow, a limiting ring, a reset spring, a suspension spring, a rigid ball for striking the tube wall interference vibration frequency and a curved flow guiding plate for changing the direction of air flow; and the one-way passage mechanism includes a gap box for connecting the end surface of the bridge module in a butting mode, an inclined plate for controlling one-way travelling of vehicles on the bridge deck, a shaping roller, a bearing shaft and an irregular impact box. According to the road bridge supporting device for reducing the influence of resonance influence, a fixed-point needle contact method is used for receiving the micro-vibration signal generated by the vehicles on the bridge deck and performs corresponding actions, and an internal structureof the pier generates different frequencies and impact actions with different forces to reduce the influence of resonance of the bridge deck to the pier.

Description

technical field [0001] The invention relates to the technical field of road bridges, in particular to a road bridge support device for reducing the influence of resonance. Background technique [0002] The resonance phenomenon is essentially a natural phenomenon that the positive feedback of energy is continuously strengthened, and it cannot be effectively released. Heat-bonded objects in nature have their own self-resonant frequency. When they are exactly equal, resonance will occur. The process of resonance is a strong positive feedback process, which can make the system absorb huge energy in a short period of time. In daily production and life, many people use the principle of resonance to change production and production methods. , but resonance will also bring unnecessary troubles and problems to people's production and life, which is particularly critical in buildings, roads and bridges, and there have been cases of bridge breakage and damage due to resonance in real l...
