一、引言地面环境试验是保证人造卫星可靠性的重要一环.为了进行环境试验,不仅要化大量人力物力建立各种试验设备,而且试验费用也是相当可观的.据国外估计,一个卫星型号的试验费用约占整个研制费用的1/5～1/3(美国军方估计约30-50%,NASA哥达德空间飞行中心估计为5-15%,欧洲空间局估计约1/3).人造卫星在发射过程中所经受的噪声、振 I. INTRODUCTION Ground environmental testing is an important part of ensuring the reliability of satellites. In order to carry out environmental tests, not only a large amount of manpower and material resources need to be set up to establish various test equipment, but also the test costs are considerable. According to foreign estimates, a satellite model The test cost accounts for about 1/5 ~ 1/3 of the entire development cost (about 30-50% estimated by the U.S. military, 5-15% by NASA Godad Space Flight Center and about 1/3 by European Space Agency).
