The Modelling of Thermal Processes Generated by the Friction of an Armature on Rails in an Electromagnetic Launcher

Abstract: The processes caused by the generation of heat due to mechanical friction at the contact surface armature/rail in an electromagnetic launcher of a railgun type are considered. The Joule heating is absent. The corresponding physical-mathematical model is presented, specific features of a numerical algorithm are described. Under certain assumptions the analytical solutions are obtained. Analytical solutions are in a good agreement with the numerical results.Note: Research direction:Mathematical modelling in actual problems of science and technic
