Abstract
An accelerated life test method for a speed reducer of an industrial robot is provided. The accelerated life test method includes: setting first load stress higher than rated load stress and second load stress lower than the rated load stress; performing an accelerated life test by loading the first load stress to first speed reducer samples; calculating a service life of each of the first speed samples in the accelerated life test; performing a contrast test by loading the second load stress to second speed reducer samples; calculating a service life of each of the second speed samples in the contrast test; and calculating an acceleration coefficient, and the acceleration coefficient is equal to a ratio of the service life in the accelerated life test to the service life in the contrast test.
