选取典型的王字形筋飞机结构件作模拟对象,用铅和Ti-1023 合金作模拟材料,分别在室温和700℃模拟金属变形情况,获得了王字形筋结构件金属流动规律。当金属在筋的交汇点处充满后不再继续流动时, 中间横筋将出现双马鞍形, 变形程度小时明显。筋间距大小只影响马鞍形开口的大小, 随着变形程度加大, 逐渐变成豁口, 最后形成折叠; 交汇点背面出现明显缩孔。当金属充满交汇点处型槽后仍能继续流动时, 马鞍形缺陷消除, 但背面缩孔更严重。
Select the typical structure of the king-shaped tendon aircraft as a simulation object, the use of lead and Ti-1023 alloy as a simulated material, respectively, at room temperature and 700 ℃ simulation of metal deformation, obtained Wang shaped reinforcement metal flow patterns. When the metal does not continue to flow after the confluence point of the tendons is full, the middle transverse bar will appear double saddle shape, and the degree of deformation is obviously small. The size of the rib spacing only affects the size of the saddle-shaped opening. As the degree of deformation increases, it gradually becomes a notch, finally forming a fold. Significant shrinkage holes appear on the back of the intersection. When the metal is full at the intersection point groove can continue to flow after the saddle-shaped defects disappear, but the back shrinkage more serious.
