A dynamic simulation device for lateral interaction between pedestrians and footbridges

Abstract

The invention discloses a dynamic simulation device for pedestrian-to-footbridge lateral interaction. The device comprises a box body. A height adjustment device is fixedly connected to the bottom ofthe inner cavity of the box body; and horizontal connection devices are fixedly connected to symmetric parts of one side, away from the bottom of the inner cavity of the box body, of the height adjustment device. Footbridge modules are movably connected to sides, close to each other, of mounting connecting members; and acting force sensors are arranged at the outer surfaces of the tops of the Footbridge modules. Pedestrian modules are movably connected to the tops of the footbridge modules. Displacement detectors are connected movably to the front side and back side of the top of a support bench. An infrared displacement detector is fixedly connected to the tops of the footbridge modules at the top of the inner cavity of the box body. The invention relates to the field of traffic and civilengineering in the field of civil engineering. The device is capable of detecting different types of footbridge modules and is operated simply; no equipment needs to be replaced; no professional is needed for operation; the difficulty of detection is reduced; and time wasting is avoided.

Description

technical field [0001] The invention relates to the technical field of lateral dynamic simulation of pedestrians and footbridges, in particular to a dynamic simulation device for lateral interaction between pedestrians and footbridges. Background technique [0002] In the past, there were a few literature reports on the vertical vibration coupling between pedestrians and bridges, but there were few studies on the lateral coupling vibrations between pedestrians and bridges. When some scholars study the pedestrian-bridge coupled vibration, they consider the vibration of the pedestrian bridge as a vibrating table, and the vibration amplitude and frequency are assumed to be a constant value, which is unreasonable. Because pedestrians and bridge lateral vibration responses interact with each other, and it is reasonable to assume the amplitude and frequency of pedestrian bridges to be a constant value if the coupling is weak, but when the pedestrian lateral swing frequency is cons...
