Necking measurement径缩测量
3)necking limit极限缩径量
1.Viscous medium outer pressure necking uses semisolid,flowable,highly viscous and certain rate sensitivity super-polymer as pressure carrying medium which can solve wrinkling problem during necking forming effectively and increase necking limit of specimen.粘性介质外压缩径采用半固态、可流动、高粘度和一定速率敏感性的高聚物作为缩径用传力介质,有效地解决了缩径成形过程的失稳起皱问题,提高了坯料的极限缩径量
2.Results show that tube blank diameters have a bigger effect on the necking forming under outer pressure in viscous medium; while the tube blank diameter turns larger,the buckling value will decrease but the necking limit increases.针对筒坯直径对黏性介质外压缩径过程的影响问题,采用试验和有限元方法进行了分析,得到了不同筒坯直径条件下1Cr18Ni9Ti薄壁管件的失稳缩径量和极限缩径量

径迹自动测量分子式:CAS号:性质:为了减轻径迹观测劳动量而采用的各种自动化扫描记录径迹的方法。现市场上已有高度自动化的图像分析仪,其基本原理是探测器的径迹图像通过显微镜光学系统放大后,投射到电视摄像机的光敏部分,将摄像机的视频信号转换成数字信号后,用计算机分析处理,给出各种所需的径迹参数。
