The invention belongs to the technical field of life prediction, and relates to a life prediction method and a device, a computer readable storage medium and electronic equipment. The method comprisesthe steps of calculating a first cycle parameter of a target component to determine a safe cycle life of the target component; calculating the life consumption rate of the target component accordingto the preset flight task and the safe cycle life; and correcting the safe cycle life and the life consumption rate to determine predicted life information of the target component. By predicting and correcting the life information of the target component, the predicted life information of the target component can be accurately determined, the dangerous condition caused by structural failure of thetarget component can be prevented, the flight safety is ensured, the purchasing cost is saved, and the method has very important significance in the aspects of ensuring the safety and improving the economic performance.
Description
technical field [0001] The present disclosure relates to the technical field of life prediction, and in particular to a life prediction method, a life prediction device, a computer-readable storage medium, and electronic equipment. Background technique [0002] Aviation gas turbine engine life consumption monitoring is an important part of engine life research. As modern aviation technology has higher and higher requirements for safety and economy, both civil aviation and the military place a very important position on the life monitoring technology of aviation gas turbine engines. Especially for military aviation turbine engines, due to the ever-changing flight missions and load conditions, this technical requirement is more urgent. Low-cycle fatigue is closely related to the stress history of components of aerogas turbine engines. Usually within the ultimate strength of the material, repeated periodic changes between different stress levels cause the material to harden or...
