The Explosive Expansion of Electrical Equipment Housings with Variable Curvature

Abstract

The work substantiates the feasibility of volute (for centrifugal fans). In contrast to the diffuser, manufacturing electrical equipment housings with variable higher requirements are imposed on the accuracy of its curvature by shells expansion with explosion energy. The dimensions. Strictly defined clearances must be provided possibility of deformation of cylindrical shells during the between its inner surface and the impeller blades. Besides, explosion of a charge that is displaced relative to the axis of the load from the motor is transferred to the casing of the symmetry of the shell is considered. A calculation method and local ventilation fan, so the casing must be sufficiently rigid. model that reflect the real picture of the pulsed deformation of a cylindrical workpiece are proposed. The developed mechanical-mathematical model allows us to consider the nature of the hardening of the material under pulsed action and the inertial components under high-speed loading.
