| 摘 要： | 针对铝合金受压及受弯构件中可能出现的局部屈曲,采用有限元方法研究了铝合金受压板件的稳定性.对国外现行规范中的设计方法进行了介绍,并对比了国外文献中的试验结果与有限元计算结果,以验证有限元方法在研究铝板受压屈曲问题上的适用性.基于有限元方法分析了影响铝板受压屈曲的各种因素,最后根据有限元的计算结果给出了铝板受压屈曲的临界宽厚比限值.分析结果表明:控制宽厚比可以有效地防止铝合金受压板件发生局部屈曲,而且所提出的板件宽厚比限值适用于铝合金受压板件的设计.

| Abstract: | As for the local buckling of aluminum alloy members under compression and bending,finite element analysis(FEA) of the stability of compressive plates is performed.The design rules for stability of aluminum compressive plates in the up-to-date codes abroad are introduced.In order to confirm the veracity of finite element models,the analytical results are compared with experimental data obtained by other scholars.The parametric analysis of local buckling of aluminum compressive plates is accomplished by FEA.T... |
