针对复合材料蜂窝夹芯板壳组成的卫星整流罩，用有限元法建立了该罩的结构动力学数值模型，编制了相应的有限元分析软件包，计算了全罩、半罩在不同边界条件下的自由振动频率和模态，并分析了抛罩时半罩的分离轨迹和气动力作用下爆炸螺栓的承载情况。
Aiming at the satellite fairing composed of composite honeycomb sandwich panel, the numerical model of the structure dynamic was established by using the finite element method. The corresponding finite element analysis software package was compiled and the full- And the free vibration frequencies and modalities are analyzed. The separation trajectory of the half-cover and the bearing capacity of the bolt under aerodynamic force are also analyzed.
