Bridge of active oscillation-controlling type
专利汇可以提供Bridge of active oscillation-controlling type专利检索，专利查询，专利分析的服务。并且PURPOSE: To secure the safety of a vehicle or the like running on a bridge and a girder by controlling oscillation due to vehicle running, wind, earthquake, and the like working on the bridge of the suspension type of an obliquely stretched bridge, a suspension bridge, or the like, actively with the use of a controller.
CONSTITUTION: At the lower section of suspension material 3 for connecting towers 1 and girders 2 to each other with, variable attenuation devices 4 and springs 5 are arranged in parallel with each other. By sensors 6 set on the girders 2, the oscillation of the girders 2 due to the running of a vehicle, earthquake, wind, and the like is detected. The detected oscillation of the girders 2 is analyzed by a computer, and the attenuation coefficients of the variable attenuation devices 4 are controlled. On the suspension material 3, resisting forces according to the attenuation coefficients of the variable attenuation devices 4 are generated, and the oscillation of the girders 2 is suppressed.
