STIFFNESS STUDY OF AN INDUSTRIAL ROBOT

Mihaela SIMION, Adrian Ioan BOTEAN, Mircea BEJAN

Abstract


For an industrial robot, stiffness is an important parameter because, over certain loading limits can affect its working accuracy. The purpose of this paper consist in stiffness study in static domain (which define the displacements) for two structure of industrial robots realized by epoxy resin, using digital image correlation method, and also, study of stresses by reflection fotoelasticity. 

Key words: stiffness, structure, robot displacement, stress, experimental
