Abstract

Speckle photography has been used to measure the instantaneous deformation of gear teeth when gears are rotating under load. Double exposure photograms are recorded with a pulse ruby laser, and correlation fringes formed by spatial filtering of the developed film. A new technique is presented for eliminating the influence of diffraction halo. A method reducing the noise level is proposed. As a conclusion, the values of gear tooth dynamic deformation are a little larger than those of the analytical calculated by finite element method in static condition, but the regulation both the measurement results and analytical ones is in good agreement.
