Electromagnetic coaxial coil accelerator for forming testing device for high-dynamic testing of materials, has stator coil winding with winding density decreasing from start or middle of stator coil winding in direction of acceleration

摘要

The accelerator (1) has a stator coil arrangement (10) including a stator coil winding (11) surrounding a stator coil holder (12), and a cylindrical cavity (14) surrounded by the stator coil winding. A translator coil arrangement (20) includes a drive pin (21) intended to be received in the cylindrical cavity of the stator coil arrangement. The stator coil winding is provided with a winding density that decreases from the start or the middle of the stator coil winding in a direction of acceleration by 20 percent.
