INTEGRATED MOVING MEASUREMENT SYSTEM FOR MEASURING DYNAMIC RESPONSES OF THE BRIDGES

摘要

PURPOSE: An integrated movement measuring system for dynamic response measurement of bridge is provided to have small early stage installation cost for dynamic response measurement of bridge since installing directly the device for the dynamic response characteristic of bridge in the vehicle and simplifying the configuration of system drastically, and to be excellent in the economic side since the sensors are not directly attached to the vehicle and maintenance and repairing are simple. CONSTITUTION: The integrated movement measuring system for dynamic response measurement of bridge includes: a vehicles(100); a sensor unit(200); and a data logger(300). The vehicles travels on the upper part of the bridge. The sensor unit is installed in the vehicle and measures the dynamic characteristic of the bridge. The data logger is installed in the vehicle and measures the measured data through the sensor unit. The sensor unit includes: acceleration sensor; displacement sensor; and strain sensor. The sensor unit is included in the wheel of vehicle shaft. The data logger is included in the driver's seat of the vehicles.
