摘　　要：针对赛代尔给出的正弦波纹板第二主刚度存在的局限性,采用数值拟合的方法,通过建立计算模型,应用各性异性板理论和数值计算方法进行大量计算,对计算数据分析归纳,拟合出新的正弦波纹板第二主刚度公式。对新公式进行了算例分析和讨论,与数值计算结果进行了印证,说明了新公式的合理性。Aiming at the limitation of the second main rigidity in sinusoidal corrugated plate given by Seidel, lots of calculations are applied to anisotropy plate models.Furthermore the second main stiffness formula of sinusoidal corrugated plate is proposed based on data Analysis and numerical fitting.The rationality of new formula are verified by the analysis of examples and comparison to the calculated results.

关 键 词：正弦波纹板 各性异性板 数值拟合 主刚度
