This research work on bird striking has a long history and already got plentiful achievemellts in theories and experiments, howevef, still a long way no doubt waits to go for sophisticated research work on it more detailed to apply to airframe engineering quantitatively in combination wth the technical reformation of the birdstrike experimelltal system in our laboratory, this thesis deeply studies and analyses the numerica1 computation and simulation methods to birdstrike dynamic response problem based on finite - elemefit - method ( fem ) numerical emulation and modem large - scale scientfic computation software
本文結合我公司
鳥撞實驗體系技術改造項目，應用有限元數值計算模擬技術及現代大型科學計算工具，對
鳥體撞
擊飛機風擋結構的動力學響應問題進行了系統學習與研究探討，初步掌握了科學計算方法，獲得了計算模擬的實踐經驗，為今後深入應用大型科學計算手段進行撞
擊類科學問題的研究以及深入應用於工程實踐奠定了強有力的工作基礎。
In summary the major research work in this thesis can be drawn as follows : 1. the techncal data and research information from woridwide aviation history about bird striking to airframe have been collected and reviewed more carefully the evolutions of bird striking load models and fem numerical compatation methods to bird strike also have been sununarized. this informational research makes great help to position further thesis work scientifically 2
本文研究工作可歸納總結為以下三個方面： 1 、較全面整理綜述了
鳥體撞
擊飛機結構在國內外航空史上的技術資料以及
鳥撞問題理論與工程研究的歷史沿革，總結了撞
擊載荷研究模型、有限元數值計算方法的發展歷程等，明確了本文研究工作的科學定位。
The scielltific computational theories and methods on bird strike to the windshield of aircraft have been systematically studied and summed up in this thesis, such as fem comptltational principles and procedures to elastic dynamic problems under the conditions of small and non - linear finite deformation, 3d viscous elastic constitutive theory and incremelltal expression under the consideration of the rate effect of non - metallic materials like the aircraft windshield, and the numerical compatational principles and key constitutions for impact - contact dynamic subjects
2 、系統學習並歸納總結了
鳥體撞
擊風擋結構問題中的科學計算理論與計算方法。按照
鳥撞問題數值計算方法逐步深入的思路，系統總結了小變形結構動力學有限元數值計算方法、有限變形的幾何非線性有限元數值計算方法、粘彈性體非線性形變的本構物理關系；對于實施復雜結構有限元動力學計算的載荷增量方法提出了對newmark差分的改進以及進行材料與幾何非線性數值計算的細致步驟。

The two muskets i loaded with a brace of slugs each, and four or five smaller bullets, about the size of pistol bullets ; and the fowling piece i loaded with near a handful of swan - shot, of the largest size ; i also loaded my pistols with about four bullets each, and in this posture, well provided with ammunition for a second and third charge, i prepar d my self for my expedition
我先把兩支短槍和一支
鳥槍裝好彈藥，每支短槍裝上雙彈丸和四五顆小子彈，大約有手槍子彈那麼大在
鳥槍里裝了特大號
鳥彈。另外，每支手槍再裝四顆子彈。出發之前，再把彈藥帶足，以作第二第三次射
擊之用。

Perhaps it was this - perhaps it was the look of the island with its grey, melancholy woods, and wild stone spires, an the surf that we could both see and hear foaming an thundering on the steep beach - at least, although the sun shone bright and hot, and the shore birds were fishing and crying all around us, and you would have thought anyone would have been glad to get to land after being so long at sea, my heart sank, as the saying is, into my boots ; and from that first look onward, i hated the very thought of treasure island
可能是因為這個也就是這個島嶼的模樣，包括它灰色憂郁的林子和巖石裸露的峰頂，以及我們可以看到和聽見的浪

鳥繞著我們四周鳴叫著捕食魚類，你會想到，在經過了這么長時間的海上航行后，任何一個人都會興高采烈地上岸去走走，但是，就像俗語說的，我的心沉到了底從第一眼見到陸地起，我一想到這個寶島就厭惡透頂。
