Abstract
The invention relates to a portable Young modulus experimental instrument. The portable Young modulus experimental instrument comprises a screw thrust augmentation apparatus, a supporting framework, a metal wire, a wedge upper glass piece, a wedge lower glass piece, a sodium lamp, a spectrometer, a microscope, a tension sensor and a hook, wherein the screw thrust augmentation apparatus is arranged above the supporting framework, the bottom of the screw thrust augmentation apparatus is connected with the hook, the bottom of the hook is connected with the tension sensor, the bottom of the tension sensor is fixed with the metal wire, the microscope is arranged at one side of the supporting framework, the spectrometer is arranged below an objective lens of the microscope, the wedge lower glass piece is arranged on a carrier platform of the microscope, one end of the wedge upper glass piece is arranged above the wedge lower glass piece, the other end of the wedge upper glass piece is fixed with the metal wire, and the sodium lamp is arranged at one side of the microscope. The portable Young modulus experimental instrument is improved on the basis of the framework of the existing static Young modulus apparatus; by utilizing a wedge interference principle, the entire apparatus can be integrated, so that the structure is compact; and moreover, the apparatus is smaller, lighter, easier to disassemble, easier to carry and good in popularization value.
Description
technical field [0001] The invention relates to the field of university physics experiment instruments, in particular to a portable Young's modulus experiment instrument. Background technique [0002] Today's static tensile Young's modulus tester has a very large device and is inconvenient to assemble and disassemble. The entire device is basically made of steel, so it is very troublesome to move this kind of experimental instrument. Furthermore, the light lever is used as a device for amplifying the deformation, so that the whole device occupies a large area and has a relatively loose structure. The principle of wedge interference is based on the principle of thin film interference, which can measure the flatness of the plane. The measurement accuracy is very high, and even small ridges or dips as small as a fraction of a wavelength can be detected from the curvature of the stripes. If there is a small angle between two very flat glass plates, a wedge-shaped air film wil...
