3 . wth application of large - scale computational software anasys - dyna , the case of elastic impact to each other of two recta - ngular cross - section rods has been implemented and also compared with theoretical results , which maks good agreement and draws very helpful practical experiences to use some techncal parameters in the program . eventually , the a real - world aircraft windshield shell structure impacted by a flying bird has been simulated through fem numerical computation , and meanime , an engineering predical experimeni of bird sttiking to the windshield in some type of aircraft has been performed 3 、應用大型科學計算程序anasys - dyna ,對彈性體碰撞進行了數值計算驗證并與理論結果對比,獲得了計算參數應用的實踐經驗;在此基礎上,進行了鳥體撞擊飛機風擋結構動力學響應的實際數值計算,與此同時安排了工程鳥體撞擊試驗,并就兩者計算結果給予了細致分析對比,獲得了良好的一致性結論。
