Abstract:
     The present invention relates to a high-speed dynamic vehicle overload detection method based on microacceleration sensor. Said method includes the following steps: (1) selecting position for mounting sensor, utilizing the deflection of static beam of bridge to calculate displacement of every point of bridge under the condition of fixed force; (2), collecting signal and measuring load weight, the bridge adopts simply supported beam model, creating movement equation when the vehicle is passed through said bridge surface, analyzing whole process of that the vehicle is passed through the bridge surface and creating vehicle/bridge correspondent function relationship formula; and (3), overload judgment, according to the vehicle type identification result making comparison of actual load weight with standard load weight prestored in data base so as to make overload judgment.
