AUTOMATION OF MATHEMATICAL MODELING OF THE INDUCTION SOLDERING TECHNOLOGICAL PROCESS

Abstract

The paper has devoted to the research and automation of mathematical modeling of the process of heating the elements of the thin-walled aluminum waveguide path when working out the induction soldering technological procedure. The paper has reviewed the method of mathematical modeling of the induction soldering technological process. In order to develop the technological process of induction soldering, an instant source of a flat rod heating is used as a mathematical model of waveguide path heating. As part of this work, a functional automated subsystem of mathematical modeling of the induction soldering technological process of thin-walled metal waveguides of cosmic aircraft was designed and implemented. The functionality of the application allows you to make an automated construction of the mathematical model of the induction soldering technological process with specified parameters, performing calculations of the temperature values of the part-components participating in the process of the induction soldering, depending on the specified sizes, structural-physical and thermodynamic characteristics, the power of the inductor and the position of the flange/couplings relative to the inductor. The obtained software product is an optimal solution for integration with the system that produces the process of controlling the induction soldering of the waveguide paths of spacecraft as a generator of mathematical models of the induction soldering process for machine learning. Comparative researches of the induction soldering models have carried out, which builds the mathematical module of the program for their compliance with the real process in permissible limits. Experiments have conducted on a software system for controlling the induction soldering process of the waveguide paths, including an induction heating generator, an inductor, a manipulator, an IPPC-9171G-07BTO industrial computer with a control console. An experimental verification of the correctness of the selected mathematical model of the induction soldering technological process and the correctness of its implementation in the developed software application has performed. The MSE values of the results of modeling and real technological processes of induction soldering have calculated. As a result of attentive and model experiments, it has established that the application of the induction heating of the elements of thin-walled aluminum waveguide paths of cosmic aircraft with a sufficiently high accuracy simulates this technological process.
