During the electromagnetic launching (EML) process, rail vibrations occur due to the electromagnetic force generated by an acute current. These vibrations result in a reduced launch velocity and decreased launch efficiency. To measure the vibration amplitude of a rail accurately and to analyze the internal relationships between current strength, rail material and vibrations, a small transient vibration...
In the paper, the simulation and the experiment were carried on a kind of planar series augmented electromagnetic rail launcher. Different from other researches on electromagnetic launcher's analysis, many practical effects were fully considered in launching process such as friction force, air resistance, heat generation and so on. Launching process and armature movement in bore were divided into...
For characterizing the series augmented railgun launching process, the study from analysis of muzzle voltage was insufficient since armature velocity, resistance and voltage drop of armature were also important to the launching process. In the present work, the variations of armature velocity, total resistance and voltage drop of armature against time were investigated based on the data of B-dot probes...
