| 摘 要： | 采用有限元方法,分别建立不同芯材、不同骨架间距、不同剖面形状,以及剖面顶角的复合材料帽型骨材加筋板模型,探讨影响复合材料帽型骨材强度、刚度的因素.通过分析芯材的影响,为复合材料船舶有限元模型简化提供了依据.综合考虑复合材料帽型骨材加筋板强度和刚度和船舶制造成本,舷侧板的最优骨架间距范围是400~500mm.在面板宽度和腹板高度一定的情况下,梯形截面的帽型骨材结构优于矩形截面,帽形骨材的最佳剖面形状为顶角为120°的等腰梯形.

| Abstract: | In order to research the influencing factors on strength and stiffness of composite cap-shape girder,using the finite element method a series of composite cap-shape girder finite element models were established with different core materials,frame space,section shape and apex angle.The analysis of core provides theoretical basis for the model simplification.Considering the strength and stiffness of composite cap-shape girder and the cost of shipbuilding.The optimal range of the frame space is 400mm~500mm of the side plate.Keeping the width of panel and the height of web unchanged,the trapezoidal section is superior to the rectangular section and the best profile shape is an isosceles trapezoid whose apex angle is about 120°. |
