Computer simulation of transformation of pulse pressure by the mechanical concentrator in technological devices such as an electromagnetic hammer

Abstract

In technological devices such as an electromagnetic hammer, a mobile part in form of a mechanical concentrator transforms impulse pressure of an electromagnetic field to an effort of stamping. The two-dimensional wave transformation of impulse pressure in an elastic concentrator with boundary conditions, conforming magnetic-pulse stamping by polyurethane, was reviewed. The implicit finite-difference algorithm of a numerical solution was designed and program was implemented. For the description of transformation of impulse pressure in the concentrator, a complex of dimensionless parameters was offered. On the basis of mathematical experiment, the transformation efficiency of pulse pressure by a mobile part was determined.
