The article describes the development of a model that generalizes integral and time-distributed parameters induction heating for forging steel rods using neural networks. Ways to improve prediction by normalizing input output are considered.
A three-phase four-leg bidirectional power converter used as an input stage of energy storage system using the inductance (L), capacitance (C), and (L) or LCL filter on grid side is considered. The article provides a variant control implementation based 3D space vector pulse-width modulation per-phase voltage control. brief analysis applied algorithms in inverter rectifier modes given. computer model has been built to investigate operating converters designated class with both balanced...
This article describes the development of a digital control system and power source for charging high-voltage capacitors in installations magnetic pulse processing various cross-sections pipes profiles. Comparison capacitor bank process depending on charge time setpoint was carried out. A diagnostics hardware protection supply also developed is described.
The paper presents mathematical modeling of magnetic-pulse metal processing. Numerical simulation the hardening process is still a difficult issue, since it requires multi-physical analysis. Namely, simulating electromagnetic, thermal, mechanical fields, as well accounting for phase transformations in structure. In this paper, result simplified pulse quenching was obtained without taking into account structural transformations. As an illustrative example, 3D model system magnetic disc knife...
The article described the process of creating protective corrosion-resistant coating zinc on product «Punch rivet» by using an electromagnetic field. currently most common methods anti-corrosion treatment do not provide required protection, therefore, rarest type protection products against corrosion is used - thermal diffusion plating. This method applying a makes it possible to achieve its preservation when sheet steel punched rivet, which improves quality connection and prolongs life...
The article describes the numerical simulation of induction system installation for creation anticorrosive coatings based on zinc in an electromagnetic field fasteners. In order to ensure high efficiency heat treatment processed products and accelerate process thermodiffusion galvanizing, it is necessary create such conditions that as much Joule possible generated products. work with different retort materials at frequencies was considered part research. obtained results modeling allowed us...
Processing of flat work pieces is one the most difficult applications magnetic pulse technology. The main difficulties using this method are uneven distribution field in piece and, as a result, low efficiency process. Numerical methods, such finite element models, widely used to solve these problems. This paper presents result research inside thin-walled piece. presented results received by two-dimensional model. Based on simulation results, features field, electromagnetic force and thermal...
