The results indicate that if the value of press stress is over certain figure, press stress and al plate ’ s thickness have little influence on sawtooth distortion for the same kind of sawtooth ; sawtooth distortion is well - regulated under static press, while it is irregular under impact press. bottom coating make great influence on bond strength of samples which can improve the value remarkably ; bonding mechanism of clad steel is mechanism of mechanical effect that sawtooth which is hooked occludes with al plate
結果表明：同種齒型，當壓應力大於一定的值時，壓應力和覆板的厚度對齒形的變化影響不大；靜壓下齒形變化比較規則，鋸齒頂端向一側彎曲成鉤狀；沖壓下齒形比較凌亂，鋸齒的頂端沒有明顯的變形；后處理對試樣的結合強度影響很大，打底試樣由於粘結層的作用，結合強度較高；機械作用機制是復合鋼板的主要復合機理，鋸齒彎曲成鉤狀和鋁板形成機械咬合。 -
On the assumption of ignoring the distortion of thickness, this paper determines the rough shape by the geometric modeling method of equal area developing using mixed mesh cell of triangle and quadrangle for the first time, presents the equal area developing arithmetic of quadrangle - triangle. on the virtual geometric symmetry axis, we puts forward the method of determining the developed coordinate of the point on the base band in the development of using regular quadrangle cell, determines the developed shape of internal structure in plane utilizing point - to - point mapping theory. furthermore, we realize the approximate developing of undeveloped - irregular boundary surface using a few triangle cells
本文結合型號研製中小曲率機翼整體壁板類零件坯料展開課題，基於板料厚向變形忽略不計的先驗假設，首創混合四邊形-三角形網格等面積展開的幾何模擬法確定壁板類零件毛坯外形，給出了混合四邊形-三角形網格等面積展開演算法；提出了虛擬分割線的概念，採用虛擬幾何對稱軸，給出了規整四邊形單元展開基帶上結點的計算方法；採用映射原理和求交演算法確定了壁板內部結構信息的展開定位。
