Bridge deflection tester / bridge deflection tester
Model: MHY-23442
Bridge deflection is a very important parameter for bridge structure. It directly reflects the vertical overall stiffness of the bridge structure and is an important basis for reflecting the linear variation of the bridge. The deflection of the bridge is closely related to the bearing capacity of the bridge and the ability to withstand the dynamic loads such as earthquakes. The scientific and accurate detection means not only has important significance for the detection of bridge bearing capacity and bridge earthquake prevention and disaster reduction, but also can improve the bridge design theory and construction. Process accumulation time experience.
MHY-23442 Bridge Deflection Tester uses long-distance non-contact photoelectric conversion method to measure the static and dynamic deflection curves of bridges. It breaks through the organic integration of optical path analysis and image acquisition. It adopts a target two lights, dynamic precision range control and flexible adaptation. A variety of different customer and site needs. The powerful processing software can derive the impact coefficient of the load and the internal force distribution state of the structure from the numerical analysis of the dynamic curve, which is helpful to judge the weak part of the bridge and the integrity of the structure. It is a practical bridge detection equipment.
Instrument principle:
The MHY-23442 Bridge Deflection Tester fixes the measured points of the bridge to be tested with a special target, so that the target and the bridge are organically combined to form a resonance, transforming the bridge vibration into a specific wavelength of the light source vibration, and analyzing the optical signal to be measured through an optical analysis system. To the special high-precision industrial CCD, the change of the central coordinate of the target image on the CCD can be used to accurately measure the longitudinal and lateral displacement of the bridge under load and its response to time. The system's K value (Kx, Ky), the actual displacement value represented by each pixel on the CCD, can be calibrated prior to measurement.
