摘要:
通过分析不同开孔的蜂窝梁,提出了确定蜂窝梁等效抗弯刚度的方法。该方法根据纯弯蜂窝梁有限元分析(FEA)结果,按照经典力学中挠度-刚度或弯矩-曲率关系式反算刚度,具有简捷、准确、经济、高效等优点。提出了蜂窝梁等效抗弯刚度的合理表达式,并以常用的六边形孔和圆孔为例,通过大量有限元分析,得到了腹板刚度折减系数表,然后进一步给出了该系数的半理论半经验计算公式。结果表明,采用该公式可快速求得蜂窝梁的等效抗弯刚度。
Abstract:
Through analyzing the different opening castellated beams, a method was put forward to determine the equivalent bending stiffness of castellated beams, which was reversely derived from the results of finite element analysis(FEA)for castellated beams under pure bending and the relationships both between deflection and stiffness and between moment and curvature in classical mechanics. It was simple, accurate, economical, and high efficient. A rational formulation was presented to express the equivalent bending stiffness, in which the reduction factor of stiffness for web with openings was obtained by finite element analysis and the method above-mentioned. Furthermore, semi-theory and semi-empirical computing equations were proposed to calculate the factor for castellated beams with hexagonal perforation and circular holes, common shapes in practice. The equivalent bending stiffness of castellated beams can be readily reckoned by using the formula.
