摘要

设计了一种桥梁疲劳监测传感器

它通过电阻不可逆变化的疲劳载荷响应机理拾取结构损伤信号。所设计的独特应变倍增器可将微弱的交变应变信号进行机械放大

使敏感元件在桥梁高周疲劳载荷作用下仍工作在敏感区。解决了疲劳敏感元件存在的较高动应变响应门槛值与结构较低动应变损伤间的矛盾

采用弓形弹性元件与硅橡胶预应力组合结构

得到了可靠性好、刚度低、放大率高及使用方便的理想结构

从而满足了桥梁结构长寿命、低应力工作特点的寿命检测要求。静载和疲劳试验说明:所设计的传感器具有很高的疲劳灵敏度、长期稳定性

完全适用于桥梁结构的高周疲劳检测。

Abstract

A new fatigue gauge for bridge monitoring is designed

the bridge structural damage can be detected by its permanent resistance change.The strain multiplier is designed for amplifying relatively weak mechanical signal so as to for working above its threshold with this device

the problem between high response threshold of the fatigue life gauge and the relatively low of the structure damage loading is solved.The structure of strain multiplier that composed of silica rubber and segment elastic element is fabricated and has prestressed.It has high reliability

low rigid

high rate of multiple and convenience to use.It is satisfactory for monitoring fatigue damage of bridge structure that usually has the character of low strain

long life.Static and fatigue experiment result gives satisfactory properties of high fatigue sensitivity

long time stability.It can well satisfy long life monitoring of bridge structure.
