Fatigue experiment method, device, equipment and machine program product

Abstract

The invention provides a fatigue experiment method, device and equipment and a computer program product. The method comprises the following steps: determining an ultimate tensile position of a target device in a second fatigue experiment period based on an actual ultimate applied pressure and a planned ultimate applied pressure of the target device in a first fatigue experiment period; wherein the first fatigue experiment period is a completed fatigue experiment period, the second fatigue experiment period is a fatigue experiment period to be completed, and the planning limit pressure of the first fatigue experiment period is the same as that of the second fatigue experiment period. And executing a fatigue test corresponding to the second fatigue test period in a manner of stretching the target device to the ultimate stretching position of the second fatigue test period as the applied pressure reaching the planned ultimate. According to the invention, the pressure applied to the tested device can be accurately controlled in a fatigue test scene in a stretching mode.
