基于车桥耦合振动的桥梁检测方法研究
A Bridge Testing Method Based on Coupled Vibration of Vehicle-bridge
摘要
Abstract
Based on theory of Coupled Vibration of Vehicle-Bridge and characters of vehicle and bridges, this paper proposes an easy way to judge the state of health of bridges' stiffness.This paper uses ANSYS with APDL language to program the module for vehicle-bridge coupled dynamical analysis in a single environment, which is verified in agreement with classic references.The paper based on module batch processing does a research when a vehicle passes weaken stiffness bridges in three uniform speeds, the change trend for vehicle acceleration peak value of the control section by coupled vibration of vehicle-bridge, and draws their 2D interactions trend figures.The results show that because the curved surface of figure is quite smooth and sensitive to rigidity reduced parameter variations in 70 km/h speed, engineers can calculate the actual stiffness by collecting vehicle acceleration peak value when vehicle pass the bridges, so as to rapidly evaluate the approximate state of health of bridges.关键词
