Experimental and numerical investigation of influence of initial liner profile to liner motion near end part of domain
Abstract:
The liner motion by the action electromagnetic forces is investigated. The band liner with plane acceleration coil is used as experimental test model for investigation of end deformations of compressible cylindric liner with longitudinal impulse current. The profile of cross section of liner end parts is empirically selected. This liner profile allows to save electrical circuit continuity when liner band is accelerated up to velocity 1 km/sec. Mathematical and numerical models of cylindric liner motion are proposed. A number of optimization calculations are carried out. Obtained liner profile allows to limit stretching deformation near support.
