Abstract

Provided is a fatigue testing device which can acquire such an amplitude of the angle of an axis of rotation of a servomotor automatically and quickly as to be set when a test is done with the fluctuation widths of a force to be applied to a work being adjusted constant. The fatigue testing device comprises deformation detecting means for measuring the deformation of the work, force measuring means for measuring the magnitude of the force to be applied to the work, spring constant calculating means for calculating the spring constant of the work, while increasing the amplitude of the angle of the rotation axis of the servomotor gradually, on the basis of the measurement results of the deformation detecting means and the force measuring means, and control means for controlling the servomotor on the basis of the spring constant calculated by the spring constant calculating means, so that the amplitude of the magnitude of the force to be applied to the work may be a predetermined magnitude.
