In the experiment , two kinds of tubes with alternative diameters and material properties , and three kinds of flat - nosed cylindrical missiles with same length and various diameters are applied . two classes including six operating modes are designed in the experiment 在實驗方面,本文采用了兩種不同直徑和材質的薄壁管試件以及三種長度相同,直徑不同的平頭彈體,設計了兩大類六種工況下的實驗。
This dissertation investigates the influences of internal press and missiles shape on deformation and rupture of a multi - span thin - walled metal tube that struck by a large - mass and slow - speed missile transversely . 103 impact tests were conducted on a thin tube ( d / t = 44 ) either empty or filled with water using a missile ( dm / t = 6 ) with various nose shapes ( flat - nosed , hemisphere - nosed and conical - nosed ) 采用三種彈體(平頭、半球形和圓錐頭,彈體直徑與管壁厚度之比d _ m t = 6 )對空管和高壓充水薄壁鋼管(徑厚比d t = 44 )進行了沖擊破壞實驗,預加工作內壓分別為0mpa , 5mpa , 10mpa和15mpa 。
A theoretical analysis of local damage in a thin ductile tube hit by a flat - nosed missile laterally is developed to predict local failure due to plugging by the beam - on - foundation model . the effect of internal press was considered , and differential equations was obtained which can predict the ballistic speed of the missile which impact the tube filled with water . it can be solved by runge - kutta method 采用地基梁模型對平頭彈體側向沖擊鋼管的沖塞型破壞模式進行了理論分析,考慮了充壓情形下內壓的影響,導出了鋼管在沖擊過程中的運動方程,可以用龍格?庫塔法進行數值求解來確定彈體沖擊充液壓力管道的彈道極限速度。
