on deformation characters. Laser scanning confocal microscope and contourgraph were used to study the effects of electromagnetic forming parameters such as voltage and die depth on material. Results show... and the traces caused by bad exhaust disappears gradually, and surface roughness decreases simultaneously in electromagnetic bulging experiments.Key words:sheet; micro-forming; micro bulging......
Effects of coil length on tube compression in electromagnetic forming YU Hai-ping(于海平), LI Chun-feng(李春峰) School of Materials Science and Engineering, Harbin Institute of Technology, Harbin...; Abstract: The effects of the length of solenoid coil on tube compression in electromagnetic forming were investigated either by theory analysis or through......
and Engineering, Harbin Institute of Technology, Harbin 150001, China)Abstract:Magnetic pressure analysis lays the foundation of the study of electromagnetic forming. There has been not enough theoretical study of magnetic pressure in electromagnetic tube-compression forming because of inhomogeneous deformation such as buckling. A numerical simulation of the magnetic pressure is carried out during......
