The modeling of eddy currents in ferromagnetic materials is impossible without information about magnetic field induction dependence of it intensity (magnetization curve). Experimental definition of magnetization curves related to technical difficulties. As a rule, reference information of that curves contains a small amount of knowledge and not applicable for direct application. In this regard the transition from original magnetization curve to its approximation is relevant. The purpose of a research is in the ch...

We considered the problem of training personnel of mining enterprises in effective application of personal protective equipment for respiratory organs - regenerative self-contained self-rescuers based on chemically bound oxygen. The engineering design task of constructing a reusable self-rescuer simulator with chemically bound oxygen supply in the absence of regenerative chemical agent was formulated. The paper describes a new design of a self-contained self-rescuer simulator, which is equipped with electric heate...
