MOVABLE MEASUREMENT SYSTEM FOR MEASURING THE DYNAMIC RESPONSE OF A BRIDGE, CAPABLE OF MEASURING A PLURALITY OF BRIDGES WITHIN A SHORT TIME AND OBTAINING RELIABILITY OF DYNAMIC PROPERTY DATA

摘要

PURPOSE: A movable measurement system for measuring the dynamic response of a bridge is provided to accurately measure the dynamic response and to measure the dynamic property data of the bridge even though an external disturbance occurs or a sensor unit on one side is damaged during driving of a vehicle.;CONSTITUTION: A movable measurement system for measuring the dynamic response of a bridge (50) comprises a vehicle (100), a protective frame (200), a sensor unit (300), and a data logger (400). The vehicle travels on the bridge. The protective frame is fixed to an axle of the vehicle to be detachable and respectively installed in both end portions of the axle. The sensor unit is mounted inside the protective frame and measures dynamic properties of the bridge. The data logger is arranged in a driver's seat of the vehicle and records data measured by the sensor unit.;COPYRIGHT KIPO 2013
