Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009. This standard proposed by China Aerospace Science and Technology Corporation. This standard by the National Aerospace Technology and Standardization Technical Committee (SAC/TC425) centralized. This standard was drafted by. Beijing Satellite Environmental Engineering Institute, Beijing Space Vehicle Design Department, China Academy of Space Technology Letter Satellite Division, China Academy of Space Technology, the Ministry of Manned Space, Aerospace Dongfanghong Satellite Co., Ltd., Shanghai Institute of Satellite Equipment. The main drafters of this standard. Xu Lanju, Fan Shichao, Zhu Jiantao, Yue Zhiyong, Li Zhengju, Feng Guosong, Wang Haiming, Chu Liyan, Zhang Li. Spacecraft vibration test method

1 Scope

This standard specifies the spacecraft vibration test requirements of the test system, test procedures, test interruption and treatment, test results evaluation. This standard applies to the spacecraft system level (hereinafter referred to as spacecraft) vibration test, sub-system-level and component-level vibration test can refer to the implementation.

2 Terms and definitions

The following terms and definitions apply to this document. 2.1 Test conditions allow deviation testconditiontolerance Test range of the actual loading conditions and test conditions allowed between the deviation. 2.2 Test over-test During the test spacecraft to withstand the test value is higher than the upper limit of the allowable deviation of the test value phenomenon. 2.3 Under-test under-test In the course of the test, the test value of the spacecraft is lower than the lower limit of the allowable deviation of the specified test value. 2.4 Multi-point average control multi-pointaveragecontrol The response to multiple control points is averaged, and the average is compared with the experimental level set point, with the difference between the two tests Way to control. 2.5 Multi-point control multi-pointextremevaluecontrol Envelope the response values of multiple control points and compare the envelope value with the experimental magnitude setting, using the difference between the two to test Way to control. Extreme control usually includes maximum control and minimum control, which correspond to the maximum envelope and minimum Envelope. 2.6 Sweeprate Sinusoidal sweep Vibration test frequency sweep rate. Usually divided into two kinds of linear and logarithmic scanning, linear scanning frequency by line Changes in the law of nature, that is, within a unit of time the frequency range of change for the set value, in units of hertz per minute (Hz/min); logarithmic frequency by Changes in the number of rules, that is, the frequency of the unit of time within the frequency range of the octave as a fixed value, in octaves per minute (Oct/min). 2.7 Not concave During the vibration test, the vibration response of certain spacecraft on the spacecraft is controlled not to exceed the specified value and the vibration input level Technology. 2.8 Response control responsecontrol Vibration test to ensure that the key parts of the spacecraft response does not exceed the limit value, the control system to measure the response of the site and in accordance with
