应变电桥 meaning in English

extensometer bridge

Strain - gauge bridge sensitivity
应变电桥灵敏度
In the paper , through the calibration test of ground load , the relationship between outputs of electrical resistance of strain gauges and the external load applied on the structure has been gotten , and then the load history can directly be deduced from the measured strain history . so the fatigue load can be compiled
本文所建立的应变法实测疲劳载荷，其主要方法是通过进行地面加载标定实验，确定所设计应变电桥输出量与结构上作用的外载荷之间的关系，再由实测应变历程直接得到载荷历程的方法。
