摘　　要：通过试验数据分析了小卫星随机振动响应特性,探讨了组件质量与小卫星随机响应的变化关系,并提出了地面随机振动响应与板面密度关系的一个经验公式。针对某小卫星发射过程中测量得到的主动段振动数据,分析总结了小卫星的主动段振动特性,着重探讨了小卫星主动段振动特性与地面试验的振动特性差异,给出了修正地面试验验证的一些建议。Based on the test data, this paper analyzes the random vibration characteristics of small satellites, focusing on the relationship between the random vibration response and the equipment mass, and proposes an empirical formula for the random vibration response and the panel area density. From the measured vibration data for a satellite during its launch, the ascend-phase vibration characteristics of the satellite is analyzed, and comparisons with the ground test are made. Finally, some suggestions on the ground tests are made.
