摘要
在航天器（卫星、飞船）的验证和鉴定过程中，结构部件和系统级的振动试验占有十分重要的地位。介绍了欧美航天部门采用底部激励方法进行航天器低频振动鉴定试验的技术现状，讨论了系统级振动试验的难点与对策，最后，评估了该项技术未来发展趋势及其有效性。
In verification and qualification of spacecraft, it is very important to carry out vibration test both in component level and in system level. The status of low frequency vibration qualification test of spacecraft by using base excitation in America and Europe is introduced, and the difficulties and solutions of vibration test in system level are discussed. At the end of the paper, the development trend and effectiveness of the technique are evaluated.
