contour forming
解釋
外形成形-
According to the theory of z - map model, the contour data is re - constructed in new sequence forming 3 - axis parallel milling tool path
根據z - map模型的原理，用行列結構對邊界點數據進行重新排列，從而得到3軸平行式加工刀軌。 -
In this paper, by using non - linear finite element software, ansys / ls - dyna, simulate a forming of auto fall to ground skeleton part, get the contour of the semi - finished product, forecast the change of the blank thickness and the probable wrinkling, cracking, and from the simulation of the spring - back, obtain the spring - back tendency. so, get technology parameters, which are inextricable to forming production. all these will pose great significant to production in theory and reality
本文運用非線性有限元軟體ansys ls - dyna對汽車落地骨架零件進行了沖壓成形的數值模擬，得出了毛坯外形，預測了成形過程中板料壁厚變化和可能出現的起皺、破裂現象，通過回彈模擬，預測了回彈趨勢，獲得了該類零件成形所需要的工藝參數，對實際生產具有一定的指導作用。 -
First read in the calculation result file i. e. d3plot, then input the correlative material parameters and ultimate strain from experiments, and the developed software will produce the forming limit stress diagram used as sheet metal instability criterion and the stress contour of the part
所開發的應用軟體，首先讀取dynaform的計算結果文件d3plot ，輸入材料的相關參數和試驗所得到的板料的極限應變，軟體即可生成用作板料失穩判據分析用的成形極限應力圖和零件的應力雲圖。 -
