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 )
採用三種彈體（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 。General rules were validated and a new rule was discovered : i. e. the shape 0f these two stress fields are same, the equivalent stress of the round corner in the bottom reached its maximum at the first phase, the equivalent stress of the edge of hole reached its maximum at the third phase, the equivalent stress of flanging with cone - shaped punch descend more than that with column - shaped punch at the fourth phase i. e. the phase of deformation completed
驗證了一般規律，也發現了新規律，即兩者的應力場形狀相同，底部圓角處等效應力在變形第1階段最大，孔口邊緣處等效應力最大出現在變形第3階段，第4階段（變形終了時）錐形沖頭翻邊的等效應力比柱形沖頭翻邊時下降更大。Tools for pressing. round punches with 60 degrees c conical head and reduced shank
沖壓工具.帶60錐形沖頭和變徑刀柄的圓沖頭So by this method, we can test the water content of the raw cement slurry through testing the velocity of the detector, it is certainly that it can test other slurry, such as paper slurry, mud slurry, mine slurry ctc. the fluid mechanics charactoristic of the slurry is complex, therefore it is difficult to establish the two - dimension or three - dimension mathematical modle to decide the relationship between the water content and the revolving speed of the detector. so the research for rotational detector in this topic is through the method of proper regressive analysis of experimental datas to establish the relation among the water content, the palse and the voltage
料漿的流體力學性能是復雜的，要想通過建立二維或三維的仿錐形旋轉式檢測頭在料漿中旋轉的流體力學數學模型，來確定料漿水分含量與檢測頭的轉速關系是十分困難的，甚至是不可能的，因此本課題對于旋轉式檢測頭的研究，是通過對實驗數據進行多元線性回歸的處理方法，建立起水分含量與紅外線對管輸出的脈沖數p及電源電壓之間的關系。Through using abaqus software, a numerical simulation of equivalent stress field of flanging deformation process with cone - shaped punch was carried out, and compared with simulation of flanging deformation with column - shaped punch
摘要利用abaqus商用軟體，對錐形沖頭翻邊變形過程的等效應力場進行了數值模擬，並與柱形沖頭的翻邊變形模擬進行了對比。Press tools. punches with 30 degrees conical head
