摘要


本文利用有限元素分析數值模擬SAE 4130鉻鉬合金鋼之成型性,針對單道次錯距順流旋型探討在旋型過程中的成型應力、應變與旋壓力之分佈規律。接著利用田口實驗法中的 直交表,主要的控制因子有PART1旋輪前導角、旋輪間距、進給速度和型模轉速等四個因子,每ㄧ因子各有3個水準,進行9組分析模擬實驗,並以田口實驗法之望小特性的品質分析法以旋胚成形中之三旋輪最小旋壓力合力為其實驗目標,經由田口法中品質特性因子反應表以及 S/N 比折線圖與反應表,顯示出影響錯距旋形中最大的兩個因子,分別是進給速度和旋輪間距。

並列摘要


In this paper, an finite element numerical simulation software, ANSYS / LS-DYNA, is used to analyze the stepped spinning forming of SAE 4130 Chrome Molybdenum Alloy Steel, and the distribution rules of spinning force, forming stress and strain under single pass of forward flow forming, Then use the orthogonal array from Taguchi method, including 4 main control factors which are the PART1 roller chamfering, roller space, feed rate, and rotation speed of mold, each of them separately have 3 levels, undertaking 9 sets of analytical simulation experiments, also take the experimental goal to be minimum spinning force, so use the Taguchi quality design method of nominal the best within the orthogonal array. In this case study, the result form the calculate S/N ratios, linear graphs and response graphs of control factors display two of the biggest factors that affects neck-in spinning , they are feed rate and roller space.
