查询词典 dragonfly

It is shown that the distribution of their veins were similar; and both wings tend to be much stiffer under upward loading than under downward loading; the area of a forewing is smaller than that of a hind wing from the same dragonfly; and the structural performance of the forewing is superior to that of the hind wing.

对具有不同起拱、起皱高度的计算模型进行静力分析，发现起拱和起皱的幅度越大，结构的刚度也越大，但单位面积上所用的材料则呈非线性增加，相应地增加了结构自重。

For comparison reason, the planar and spatial models based on a forewing structure were analysed, it is shown that the cambered corrugation in the wings can improve the flexural stiffness of dragonfly wings effectively; the veins distribution and their size variation in different zones are quite reasonable.

对前翅平面模型和立体模型的静力性能进行了对比分析，发现翅膀中的起拱、起皱结构可显著提高蜻蜒翅膀的弯曲刚度；分布在翅膀不同区域的翅脉横截面尺寸与其受力大小是完全相适应的。对翅膀模型分有膜、无膜两种情况进行对比分析，得出翅膜中产生的膜应力刚化效应可有效改善翅膀结构的刚度。
