摘要
给出随集中载荷或均布载荷带硬芯膜片的应力、刚度和有效面积的计算方法，并给出实测结果。计算和实验比较证明，该方法是可行的。
A method for calculating stress stiffness and effective area in a flat circular diaphragm with a hardpan in the center subjected to concentrated or even-distributed load is introduced. The calculation and the experimental results were compared. The validity of the method suggested in the paper is confirmed by the experimental results.
