摘要
新型复合材料圆柱壳结构——金属箍增强复合材料圆柱结构(HRCC)由复合材料壳体,两端内、外金属套筒及中部的内、外金属箍等组成,为使其获得更高的承载效率,对内、外金属箍几何尺寸和间距进行了优化设计。首先通过试验对有限元计算的准确性进行了验证;然后将内、外金属箍宽度、厚度及金属箍间距作为独立因素,以HRCC的承载效率为优化目标,基于有限元方法设计了多因素、多水平正交试验;最后利用极差分析法对正交试验进行影响权重分析,得到最优参数组合,并重新建模进行有限元模拟。结果表明,优化后的HRCC承载效率提高了10.2%。
A new type of composite cylindrical shell structure-metal hoop reinforced composite cylindrical structure(HRCC)is composed of composite shell,inner and outer metal sleeves at both ends and hoops in the middle.In order to obtain higher load-carrying efficiency,the geometric dimensions and spacing of inner and outer metal hoops are optimized.Firstly,the accuracy of the finite element calculation is verified by experiments,and then the width,thickness and spacing of the inner and outer metal hoops are taken as independent factors,and the bearing efficiency of HRCC is taken as the optimization objective,based on the finite element method,multi-factor and multi-level orthogonal experiment is designed,and the influence weight of orthogonal experiment is analyzed by range analysis method,and the optimal parameter combination is obtained.The results show that the bearing efficiency of HRCC is improved by 10.2%.
