Abstract

The invention relates to a spacecraft thermal control function system health assessment modeling method, which comprises the following steps: a, dividing a spacecraft into different function systems,and performing function system layer modeling according to each function system; b, performing component layer modeling according to each component in each functional system of the spacecraft; c, distributing the health state of each part to different indexes, and carrying out index layer modeling; and d, performing parameter layer modeling according to each index. According to the model constructed by the invention, the testability design and the health assessment are directly associated by the bottom layer parameters; the testability design and the health assessment form a closed-loop relationship, so that the health assessment is associated with the reliability design, the testability design and the health management at the same time, the whole stage and all directions of the health management are integrated, and the difficulty of health management construction is reduced to a great extent.

Description

technical field [0001] The invention relates to the field of spacecraft health management and modeling and simulation, in particular to a health assessment modeling method for a thermal control function system of a spacecraft. Background technique [0002] The complex spacecraft system is composed of multiple stand-alone machines or components. The harsh orbital environment will bring various forms of failure. Once the failure is not detected and disposed of in time after the failure, it may lead to serious consequences of destruction of the aircraft and human death. Health management technology monitoring can monitor, evaluate, predict and deal with faults in real time, and is a powerful tool to ensure the safe operation of satellite systems. [0003] Health assessment technology is the key technology of health management. Based on the analysis of historical data and monitoring data, it comprehensively evaluates the health status of the system through various evaluation alg...
