摘要
对测量金属丝的杨氏模量实验进行改进,采用光纤传感器来代替光杠杆,通过测量发射-接收探头与平面镜之间的距离测量已知加载情况下金属丝的微小伸长,从而得到金属丝的杨氏模量.
The traditional experiment device to measure Young modulus of wire was improved by replacing the optical lever with an optical fiber sensor.By measuring the distance between the light emitter-receiver and the mirror,the slight elongation of the wire under a known loading could be obtained and then the Young Modulus of the wire could be calculated.
