管系动应变测量和疲劳寿命评估(Dynamic Strain Measurement and Fatigue Life Assessment of Pipeline )
管系 动态应变 疲劳寿命
2008/11/19
某核电站调试期间发现电动泵入口管系在小流量运行时振动强烈。本文作者运用电测方法测量了管系实际动态应变,根据ASME和BS标准估算了管道的疲劳寿命。
Jacket effect on strain measurement accuracy for distributed strain sensors based on Brillouin scattering
fiber optics sensors Brillouin scattering strain monitoring jacket effect
2011/4/28
Fiber jacket has a function of protecting fibers from harsh environment; it also has an impact on the measured strain accuracy. In this paper, we report on our study of jacket effect to distributed Br...
