Abstract

Abstract Modeling of connections in CAD class systems enables conducting simulation tests of entire structures. It gives the opportunity to reduce costs and speeds up the design process itself. Programs using the finite element method (FEM) are the oldest (over 40 years of history) and the most popular tools for modeling objects and physical processes. It is an absolutely necessary component of the knowledge of every modern engineer. In contrast to physical modeling (see below), in which quite approximate models are used, the MES program can model structures in great detail. But the calculation time for this reason can be relatively long. However the advantage of using CAE systems is the ability to understand the behavior of the object in real conditions, to conduct a numerical experiment under the influence of: load, vibration, temperature, etc. with the use of computer calculations and simulations. The paper presents the use of an advanced CAD / CAE class system for modeling complex technological joints of mechanized mining supports manufactured using the welding technology. One of the most important problems in manufacturing and repairing of mining support using the welding technology is the method of welding the dissimilar joints and analysis of its characteristics. It is particular important for the repairing procedures. A case of such approach is presented in the present paper.
