摘　　要：基于经典层合板理论和刚度等效原理,推导了复合材料帽型加筋层合板典型板元的等效面内刚度和等效弯曲刚度的理论解,通过具体算例,将多种工况下典型板元的受力响应和Abaqus有限元计算结果进行比较,结果显示理论解和有限元计算结果吻合较好,说明理论计算方法是准确可靠的。本文的研究成果可应用于复合材料加筋层合板和单板骨架式复合材料船体结构的刚度计算。Based on typical laminates theory and equivalent stiffness principle,this paper deduced the theoretical solutions of equivalent in-plane stiffness and bending stiffness of typical plate element of composite cap stiffened laminates.By concrete example,the theoretical solutions and Abaqus FEM solutions are compared,the results shows that both solutions are in good agreement and the theoretical calculation method is accurate and reliable.The research results of this paper can be applied on stiffness calculations of composite cap stiffened laminates and composite ship with single-plate frame hull structure.
