Fatigue failure prediction apparatus of mechanical structures

摘要

The present invention relates to a machine structure for receiving a load; And a portion to be monitored for fatigue damage of the mechanical structure is designed as a monitoring portion on the mechanical structure with a stress similar to that of the monitoring portion and has a shorter fatigue life than the monitoring portion, And the fatigue damage of the monitoring unit is predicted to be broken, thereby preventing the fatigue failure of the monitoring unit.
