摘要
对构造上各向异性板,如波纹板,当板厚达到一定数值时,赛代尔的第二主向刚度公式不再适用。依据平板抗弯刚度公式,提出等效惯性矩的思想,构造了波纹厚板新的第二主向刚度公式。通过对四边简支波纹板的计算和试验测量,证明赛代尔的公式较适用于薄板,而对厚板给出的第二主向刚度公式接近试验值。
For a textural anisotropic plate, such as corrugated plate, the second main stiffness formula of Seydel is not applicable when the thickness of plate increases to a certain value. According to bending stiffness formula of the flat plate, the idea of equivalent inertia moment is proposed, which constitutes a new second main stiffness formula for corrugated plate. By means of calculation and experiment on the corrugated plate, which is hinged support in all boundary, the results prove that the formula of Seydel is applicable for the thin plate, and the second main stiffness formula is applicable for the thick plate.
