Abstract

The invention relates to a system for life evaluation and forecasting by repeatedly using a carrier and a method for life evaluation and forecasting by repeatedly using the carrier, and belongs to thetechnical field of spacecraft maintenance and guarantee. Specific to the problem of repeat use of the carrier through many complex severe environments, sensors distributed on the carrier are mainly used for collecting data of an aircraft component in real time; a weighting and dimensionality-reduction algorithm is applied to perform weighting and dimensionality-reduction on part component data required to be monitored, thus the index quantification difficulty of life evaluation and forecasting is solved; on this basis, the residual life of the part component is matched by combining with the inherent property data of the product and others; the sensor data updated in real time can update the fitted residual life curve, thus the forecasting result is more exact and reliable.

Description

technical field [0001] The invention relates to a system and method for evaluating and predicting the life of a reusable carrier, belonging to the technical field of spacecraft maintenance and support. Background technique [0002] How to evaluate and predict the life of a reusable vehicle directly affects the vehicle's mission objectives, mission cycle, re-execution mission preparation time, and mission costs. As far as the reusable vehicle is concerned, it needs to go through ①ground preparation stage -> ②ascent stage->③in-orbit operation stage->④re-entry return stage->①ground preparation stage->..., various flight mission stages are harsh Environmental conditions lead to complex force, heat, electromagnetic and space environment for the vehicle. Different from traditional vehicles, reusable vehicles need to realize re-entry and return and perform missions again after landing inspection and maintenance, and a series of test and maintenance guarantee work ne...
