Abstract
The invention provides an eddy-current guardrail anti-collision device. The eddy-current guardrail anti-collision device comprises a fixed steel plate, outer barrels, rotating steel plates, racks, U-shaped springs, rubber warning posts, U-shaped spring connection holes A, fixing piles, rotating steel plate connection holes, gears, central rotating shafts, fixed magnets, middle barrels, moving magnets, damping fluid, rotating steel plate connectors, U-shaped spring connection holes B, rack connection parts, rubber plates and a graphene coating. The device is mounted on two sides of a road, andwhen a running vehicle deviates and bumps into a guardrail, the rotating steel plates rotate, the U-shaped springs generate force opposite to a collision direction by compression deformation to assistthe vehicle in driving direction correction; meanwhile, the rotating steel plates drive the middle barrels and the outer barrels to rotate in opposite directions through a transmission system, then conductors and permanent magnets have relative motion, energy dissipation is realized by eddy-current damping and viscous damping to reduce interaction force between the vehicle and the guardrail, andaccordingly safety of the vehicle and a driver can be guaranteed.
Description
technical field [0001] The invention relates to the technical field of guardrail anti-collision devices, in particular to a novel highway guardrail anti-collision device using eddy currents, which is suitable for buffering and vibration-reduction control of impact loads of road safety guardrails. Background technique [0002] With the development of science and technology, automobiles have become a necessary travel tool for every household, which brings convenience to people and also brings safety hazards to people. At present, traffic accidents have become the "No. 1 hazard in the world", and China is one of the countries with the largest number of traffic accident deaths in the world. During the driving process of the vehicle, it is inevitable that accidents will occur and crash into the roadside guardrail, causing huge damage to the vehicle. According to data, nearly 1 / 3 of the deaths in our country every year occur in single-vehicle accidents where the car collides with ...
