Abstract

This paper presents developments performed on photoelastodynamic bench of ENSICA's Department of Mechanical Engineering. Classical wave, vibrating, shock and rotating parts theories, were compared with colour pictures of isochromatic lines obtained with rapid camera and urethane resin specimens. For non-linear shock and large deflection, explicit code LSDYNA has been used. Then, the facility has been used to analyse dynamic work of gears for power transmission, in comparison with numerical computations. These developments have lead to demonstrations now included in engineering general courseware, about stress analysis : theory of elasticity and dynamics of structures. Gear visualisation have been included in integrated France-Canada developments concerning dynamics of transmission, as a complement with theoretical models and experimental acoustic analysis of functioning gears.
