Selection of the main dimensions of the electromagnetic impact machine with a through axial channel

Electromagnetic impact machines with through axial channels used for sampling and transporting samples of rock and building materials and providing immersion in the ground of long longitudinally unstable rods expand the possibilities of working in the mining and construction industries. The paper considers the influence of the dimensions of the axial channel of an impact electromagnetic machine on the existing range of extreme ratios of its main geometric dimensions that satisfy the criterion of the minimum mass of the volume of active materials. The studies are carried out using the numerical calculation of the magnetic field by the finite element method using the FEMM (Finite Element Method Magnetics) software package. The results of the numerical calculation of the magnetic field in the active volume of an electromagnetic machine are presented in the form of graphical dependencies. Their analysis makes it possible to obtain the recommendations on the value of the ratios of the main geometric dimensions. The search for the extreme values of the ratios of the main dimensions is carried out by the method of rationalized enumeration using polynomial regression. The ranges of optimal ratios of the geometrical dimensions of an electromagnetic machine depending on the ratio between the through channel and hollow striker diameters are obtained with respect to minimum volume and mass of active materials. The method of preliminary calculation of the main geometrical dimensions of an electromagnetic machine with the through axial channel satisfying the criterion of minimum volume of active materials is proposed. The recommended relations of the main geometrical dimensions give possibility to reduce the consumption of the active materials of single-coil impact electromagnetic machines with the through channels saving their operating characteristics.
