Abstract
A lifespan diagnosis device for a motion guidance device including: a stress calculating means which calculates stresses during movement for each of virtual segments, the stresses during movement being stresses that occur in each segment during a movement of the moving member; a counting means which counts, for each of the segments, on the basis of the amount of displacement, the number of occurrences of the stresses during movement which repetitively occur with waving during a movement of the moving member along the track; and a diagnostic means which calculates, for each of the segments, a lifespan exhaustion ratio on the basis of magnitudes of the stresses during movement and the number of occurrences of the stresses during movement, and which diagnoses the lifespan of the motion guidance device on the basis of the calculated lifespan exhaustion ratios of the respective segments.
