摘要
针对卫星天线阵分别建立不同联接方式的计算模型、相同联接方式的不同计算模型,应用有限元方法分别计算其动态特性。通过计算结果对比分析,发现点耦合联接的整体结构模型相对于粘接方式联接的整体结构模型和粘接方式联接的对称简化整体结构模型计算结果更精确、更符合实际。
The calculation models with different way of connection and the different calculation models with the same way of connection have been respectively established for the aerial array attached to the satellite. The dynamic properties of the above models have been calculated separately by the application of finite element methods. Through contrasting and analyzing, the result of the whole structural model with the coupling connection, comparing with the whole structural model with sticking connection, and of the symmetrical simplified whole structural model are proven to be more precise and more practical.
