摘要
通过对周边固定大长宽比矩形薄板受均布载荷挠度的实验,发现数据与用目前工程中使用公式的计算结果有较大的误差。通过对约束条件的分析和理论推证,得到了新的计算公式。实验证明,新计算公式的计算结果与实验结果相比,误差较小,提高了计算精度,并且有较宽的适用范围。
In the experiment of deflection of rectangular plate with fixed boundaries and large ratio of length to width under uniform surface load,it is shown that the data difference between experiment and formula normally adopted in engineering is quite large.By analysis of the constraint conditions and theoretical derivation,new formulae,which have less error and wider application range,are brought forward.
