摘要
对简谐载荷作用下的简支板应变分布进行了谐响应理论分析,根据分析结果确定了光纤光栅(fiber-bragggrating,FBG)应变传感器的安装位置和数目,并利用FBG分布式传感网络对简支板的动态应变进行了测量。实测结果与理论计算相符,证实了该方法的有效性。
Harmonic response of strain distribution of a simply supported plate under simple harmonic load was theoretically analyzed.According to the results,fixing position and numbers of fiber bragg grating (FBG) strain sensors were ascertained,and dynamic strain of the plate was measured by using FBG distributed sensing network.Agreements between experimental results and theoretical simulation verified the validity of this method.
