正文 第31章 全新的工程模型(第1页/共3页)
此时方振也把草稿纸还给了常浩南:
“师弟,最后几页纸的内容能不能讲一下,我实在是看不太清楚你写的是什么……”
他总算意识到自己之前离谱地低估了对方的能力,竟然还准备从自己的成果里面抽一点出来给人家做毕业设计……
方振无比庆幸自己当时没把这个话说出来,否则现在大概比姚梦娜还要丢人——如果纸上写着的东西没有错误的话,那常浩南在刚刚这一个上午三个小时的时间里取得的成果,比他博士三年加起来都要大。
实验室里的所有人都已经围了过来。
“唔……写到这的时候进状态了,确实有点乱。”常浩南当然不知道方振内心的想法,只是接过来看了两眼:
“这一段我是要把机翼模型在静平衡位置处进行线化,计算出机翼在配平状态下的线化模态……”
“假设大展弦比机翼在给定的飞行条件以及自重下的静变形为u,且机翼在静平衡位置处做微幅振动,则机翼的上各点的位移可表示为……”
“对于考虑了几何非线性因素的大展弦比机翼模型,提取其非线性正交模态后,结构的运动方程就可以根据模态叠加原理转换至模态坐标下,具体形式是就是纸上面标着33号的那个方程。”
“再将其改写至拉普拉斯域,并引入人工阻尼g,据选取一系列适当的模态,即可建立频域内的广义气动弹性方程……”
“……”
虽然这并不是个纯数学问题,但无疑需要很深的数学功底,因此在常浩南讲到一半的时候,除了方振和姚梦娜之外的所有人就都已经撤了。
听不懂!
而听完了全程的两位博士对视一眼,都从彼此的眼神中看出了震惊。
他们听懂了,并且没有发现整个过程有什么逻辑上的漏洞。
因此接下来就是修改程序,按照草稿纸上的理论对机翼颤振情况进行分析,算出颤振临界速度。
如果计算结果和实际结果能对上的话……
那就说明常浩南创造了一个新的工程模型。
虽然还称不上是一套完整的理论,但也绝对是能在航空工业史上留下名字的成果了。
只用了一个上午的时间!
“我来弄程序!”
虽然性格上是个比较保守的人,但这并不意味着方振没有梦想。
而如果能参与到这个模型的验
