| 摘 要： | 文章通过对星载天线振劫响应问题的分析，提出了提高设计质量和改进设计方法的建议：首先，在抽象和归类的基础上，将上／下层天线结构简化为二级隔振系统：通过对上／下层二级隔振系统分析，推导了传递函数。然后，通过改变下层结构的阻尼特性、质量特性和刚度特性，定量地分析了不同参数情况下传递函数的变化情况，最后．根据分析和计算结果，提出了一般的设计规则和建议．

| Abstract: | By vibration response analysis of satellite antenna, some methods which can improve design are suggested. First, based on the summarizations and classifications, two layers antenna structure is simplified into a two-stage vibration isolation system. Through analyzing of two-stage vibration system, a transmission function is givem Then, by adjusting the damping ratio, stiffness ratio and mass ratio, the change of transmission function depending on different parameters is calculated. Finally, bases on our analysis and calculation, some suggestions are given. |
