本文介绍关于用复合材料制成的柱形局部屈曲试件(低直径-厚度比)的试验结果,其试件为复合材料与全属粘接的台阶式接合结构,并且为一种以设计极限载荷的118％破坏的硼/环氧树脂增强的论证性桁架。对所有试件和论证性桁架的试验结果和分析进行了比较。在介绍采用插入芯棒的方式制造复合材料管材方法的同时,还介绍了关于设计正交各向异性的均质梁柱分析的最优技术。把硼/环氧树脂增强的钛合金管式桁架与全钛合全结构相比,其减重约24％。
This paper presents the results of tests on a cylindrical partially buckled specimen (low diameter-thickness ratio) made of a composite material, the specimen being a stepped bonded structure of a composite material and a wholly bonded type, 118% Failure of the Defeated Boron / Epoxy Reinforced Demonstrative Truss. The test results and analysis of all specimens and the demonstration truss were compared. While introducing the method of manufacturing composite pipe by means of insert core rod, the optimal technique of homogeneous beam column analysis for designing orthogonal anisotropy is also introduced. The boron / epoxy-reinforced titanium alloy tube truss has a weight loss of about 24% compared to the all-titanium all-steel structure.
