摘　　要：为了实现大扰动下的响应围裙特性参数计算分析,基于向量式结构力学,提出一种计算大扰动下围裙复杂成型的向量式有限元法。运用该有限元法进行了围裙特性参数计算,并全面分析了囊压比、航速、触水深度和几何参数对响应围裙特性参数的影响,得出的结论可为响应围裙的设计提供一定参考。For the study of characteristic parameters of responsive skirt under large disturbances, a FEM method based on vector structural mechanics was proposed to calculate the complex skirt shape under large disturbances. Based on this FEM method, the influence on responsive skirt characteristic parameters of bag cushion pressure ratio, speed, draught and geometric parameters have been discussed. The results can provide important reference for the design of the responsive skirt.
