Problems solved by technology

For the boundary conditions at both ends of the long suspender close to the bridge tower are close to hinged, the spectral method can ensure sufficient accuracy. For the boundary conditions of the short suspender close to the mid-span, there is a big difference from the ideal boundary condition, and the calculation error of the above method is relatively large. The frequency law no longer applies

Abstract

The invention discloses a suspension bridge suspender force measuring device. The suspension bridge suspender force measuring device comprises a main cable, a suspender and a stiffening beam and is characterized in that two ends of the suspender are respectively connected with the main cable and the suspender, a flatbed truck is arranged on the stiffening beam and provided with chassis, the chassis is connected with the suspender through an upper hydraulic telescopic rod and a lower hydraulic telescopic rod, an upper hydraulic support rod is arranged between the upper hydraulic telescopic rodand the lower hydraulic telescopic rod, a lower hydraulic support rod is arranged between the lower hydraulic telescopic rod and the chassis, and a measuring instrument is arranged on the suspender. The suspension bridge suspender force measuring device has the advantages that the boundaries, at two ends of a frequency measuring section, of each suspender can be adjusted to be close to fixed boundary conditions, and accordingly suspender internal force measuring precision can be increased greatly; the device is assembled to the truck, so that measuring efficiency is increased.

Description

technical field [0001] The invention belongs to the technical field of precise measurement, and in particular relates to a suspension bridge hanger force measuring device. Background technique [0002] The suspension bridge is composed of anchorage, bridge tower, main cable saddle, loose cable saddle, main cable, cable clamp, suspender and stiffening beam and other components. It has the characteristics of strong spanning ability, high economic index under specific geological conditions, simple and beautiful line shape, etc. , It has been widely used in the construction of my country's transportation industry. [0003] During the operation of the suspension bridge, the main force transmission path of the load is: stiffening girder → boom → main cable → bridge tower and anchorage. one. [0004] At present, the method of measuring the internal force of the boom is mainly the frequency method. The frequency method is to indirectly obtain the internal force of the boom by meas...
