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。
For the satellite antenna array, different calculation models of different connection methods and different calculation models of the same connection method are respectively established, and their dynamic characteristics are respectively calculated by using the finite element method. Through comparative analysis of the calculated results, it is found that the overall structural model of the point-coupled joint is more accurate and more realistic than the global structural model of the bonded joint and the simplified symmetrical simplified integral structural model of the bonded joint.
