    摘要:

    随着夹层结构材料在工程领域中的不断推广应用,现有夹层结构材料逐渐不能满足工程设计要求,迫切需要开发高效、节能并易于加工的新型夹层结构材料。结合重大应用背景(主要包括超轻高强金属夹层结构材料在汽车、航空航天、机械等领域的高质量、高能耗装备中的应用),提出并构建一种新型“类蜂窝”夹层结构材料,研究夹芯层的力学性能等效方法,夹层结构的强度、刚度和固有频率特性,以及基于失效准则的结构材料一体化设计方法,为轻量化材料和结构的创新设计提供新的思路。

    Abstract:

    With the sandwich structure materials' application and promotion in the field of engineering continuously, existing sandwich structure material gradually cannot meet the design requirements. It is very urgent to develop new sandwich structure materials of high efficiency, energy saving and easy to process. The project puts forward and constructs a new kind of class-honeycomb sandwich structure material combined with important application backgrounds that super light and high strength metal sandwich structure materials are applied into the high weight and high energy consumption equipments of automobile, aerospace and machinery and so on. This research involve: mechanical properties equivalent method for the class-honeycomb sandwich structure and its core; Strength, stiffness and inherent frequency characteristic and failure criterions of the class-honeycomb sandwich structure; based on the failure criterions constructing the multiple-constraint models of the class-honeycomb sandwich structure. The research tries to put forward a new method for innovative design of lightweight material and structure and new ideas of lightweight technology research in theory and practice.
