【 摘 要 】

Young's modulus is an important physical quantity to describe the deformation resistance of solid materials, and it is one of the commonly used parameters in engineering technology. A device for measuring Young's modulus of wire by automatic counting of interference ring is mainly composed of an automatic counter of interference ring, a Michelson interferometer, a tension tester and a wire to be tested. The elongation of wire is recorded by recording the number of interference fringes and rotating coarse adjusting knob by using the automatic counter of interference ring, and at the same time measuring the tension applied on the wire to be measured by using the digital explicit tension measuring device, and substituting the calculation formula. The Young's modulus of the wire to be measured can be obtained directly.
