| 摘 要： | 介绍用迭代方法求解直升机结构承载能力的过程,求解非线性方程。计算时,首先假定结构是给定的,求出结构最大承载能力;以某一直升机模拟试验件为例,算出各试验件每一元素的应力、位移、屈服情况、失稳部位随着加载过程而变化情况以及最大承载能力等。计算结果与试验结果吻合很好。

| Abstract: | Process solving helicopter structural bearing capacity in iteration method and solution of non-linear equations are present in the paper.The maximum structural bearing capacity is solved in computation,supposed a structure was given,then stress .displacement yield ,Variation of position of stability loss during loading and maximum bearing capictity etc of every element of specimens with specimens of a certain helicopter as test specimens are calculated.The calculation results have better coincided with the tost results. |
