Design on Deformation Measuring System of End Face of Mechanical Seals Based on Binocular Vision Digital Image Correlation

Based on binocular vision digital image correlation method,the deformation measuring system of end faces of mechanical seals was designed. The hardware of this system consists of high-speed digital cameras,lenses,capture cards,light sources,a calibration plate,a support system,and a server. And the software was developed on the basis of the binocular vision digital image correlation method. By this system,the surface three-dimensional topography and the surface deformation of the mechanical seals under the force and thermal loads can be achieved. In addition,it has advantage of simple structure and convenient operation. This is important for studying on the key factors which affect the end face deformation of mechanical seals and exploration of measures to decrease their deformation.
