Forecasting system for high-magnitude test condition of sinusoidal vibration test for spacecraft

Abstract

The invention discloses a forecasting system for a high-magnitude test condition of a sinusoidal vibration test for spacecrafts; the forecasting system comprises the following six modules: (1) a low-magnitude (feature-level) sinusoidal vibration test condition and test data input module; (2) a high-magnitude test condition input module; (3) a sunk condition criterion, part and component one-machine test condition input module; (4) a high-magnitude test condition forecasting and analyzing module; (5) a high-magnitude test condition displaying and adjusting output module; and (6) a test condition and analysis management module. The forecasting system provided by the invention can be directly applied to the vibration test of the spacecrafts and can be used for forecasting the high-magnitude test condition in combination of a low-magnitude (feature-level) sinusoidal vibration test condition and test data according to a given sunk condition criterion and a part and component one-machine test condition. The forecasting system is convenient for condition design and improves the effectiveness of tests and efficiency.

Description

technical field [0001] The invention relates to a high-level test condition prediction system for a spacecraft sinusoidal vibration test, which is directly applied to the spacecraft vibration test. Background technique [0002] The sinusoidal vibration test is an effective means to assess the structural performance, environmental adaptability and assembly level of the spacecraft. Generally, the sinusoidal vibration test will carry out the conduction test, the first characteristic level test, the high level test (acceptance level test, the quasi-identification level test, the identification level test), the second characteristic level test, and compare the two before and after the high level test. If the results of the sub-characteristic level test are consistent, the spacecraft is considered to have withstood the assessment of the high-level test; otherwise, it is considered that some links in the spacecraft have failed. Due to the difference between the shaking table test ...
