    摘要:

    以复合材料层合板为基本材料设计了一种结构新颖的定向破坏复合材料层合壳体结构,在导弹与
    该壳体结构的初始接触区域预制缺陷区,导弹发射时以四瓣形式开裂,大幅度提高了导弹的发射效率。利用ANSYS
    有限元模拟分析软件,通过强度分析确定了最佳铺层设计方案,单层板厚度为0.2 mm,采用基体本身加强预
    置缺陷区的[0°/90°/ ±45°]2S 铺层方式。该种铺层方式的爆破载荷为0.21 MPa,最小顶破载荷为1 kN,完全能够
    满足其在工作环境下既能承受一定的压力不漏气又能在较小的顶破载荷下自行破裂的设计要求。

    Abstract:

    A new kind of structure of the directional composite laminated shell structure is designed in this paper,
    based on the composite laminated plate as the basic matieral. The weakness is precasted in the missile and the initial
    contact area of the shell structure precast defect area. The missile launch cracking in the form of four petals,and
    the efficiency of the missile launch is improved greatedil. Through the finite element simulation analysis software ANSYS,
    the design scheme of the layer is determined by the strength analysis, namely 0. 2 mm of the thickness for the
    single plate,the weakness is strengthen using the matrix itself,the kinds of the layer methods for [0°/90°/ ±45°]2S,
    the limit load is 0. 21 MPa and the minimum bursting load is 1 kN of the layer, so that it can meet the design requirements
    to bear certain internal pressure and in smaller bursting load to crack in the work environment.
