本文针对大型复杂的民用飞机全尺寸试验机上所发现的局部裂纹,提出一种由全机内力解模型逐级细化到局部结构细节模型的分析方法,快速有效的找出了裂纹发生的原因。对于大型复杂结构在载荷工况较多情况下的局部细节分析具有较高的参考价值。
In this paper, aiming at the local cracks found on the large-scale and complex civil aircraft full-scale testing machine, a method of analyzing the whole-body internal force model to the details of the local structure step by step is proposed, which can quickly and effectively find out the cause of the crack. It is of high reference value for local detail analysis of large and complex structures under more load conditions.
