Abstract

When creating new objects, reverse engineering technologies are often used. Unlike traditional (direct) engineering, when a product is created from scratch, with reverse engineering, a new product is developed based on a prototype, which significantly saves money and reduces time.

The purpose of the study is to systematize and evaluate the main approaches of reverse engineering of modern electromagnetic contactors.

Materials and methods. The paper uses comparative analysis and generalization of the results in graphical form, and computer mathematical modeling in the COMSOL software product.

Research results. A variant of the content and sequence of stages which is typical of reverse engineering of an electromagnetic contactor is presented. The stages of reverse engineering of an electromagnetic contactor are formulated and analyzed in detail. The main part of the design consists in the development of a 3D model of the prototype based on the results of digitization of its parts, as well as modeling and research of the main components (contact and magnetic systems) using their computer mathematical models (model experiments). As an example, the modeling of the magnetic system of a DC contactor is considered in detail. Based on the results of optimization and design development, a 3D model of the new contactor is developed.

Conclusions. A method of reverse engineering of an electromagnetic contactor based on the use of modern CAD and CAE systems is proposed. The main difference of the technique is the optimization of the design based on the results of model experiments performed with minimal time in standard software products that do not require expertise.
