Structural optimization of stationary plates of industrial and technological equipment

The paper considers the examples of technical production tests to determine the bearing capacity of the structural elements of technological machines and equipment used in various industries and agriculture: the bearing beam of the front axle of the combine harvester, fixed support plates of the apparatus for the production of plastic containers, bearing profiles of the thermal press designed to connect the ends of conveyor belts of various sizes, etc. The nature of stress distribution and deformations in the elements of the existing variants of technological machines and equipment allowed to identify shortcomings in their design. Analysis of calculations in ANSYS environment allowed to recommend variants of models of technological machines and equipment with better indicators of bearing capacity. This will greatly improve their reliability and performance.

Over the past decade, the number of accidents in steel-framed buildings has been decreasing thanks to advanced approaches to cause analysis. In the presented article, a brief overview of the existing common design solutions of frame joints of the rack with the crossbar is made. A finite element design model of the structure under consideration has been made in accordance with the most common design solutions based on the experience of designing construction design organizations. The analysis of the local buckling of a steel structure element, which had cases of collapse in real life, was carried out. The results of the structural analysis of the structure without the presence of any defects were assessed, and the dependence of the bearing capacity of the structure on the presence of defects and the degree of their development was presented in a graphical form. The presence of a sensitive parameter of the structure under study was determined and the direction of further research of the frame connection of the rack with the girder was determined.

The article is devoted research of process equipment in the simulation of the stress-strain state of load-bearing elements in the environment of ANSYS. The obtained results are consistent with the data of preliminary calculations and confirm the performance of device. The device for connecting the ends of a conveyor fabric-rubber belt by a vulcanization method is a set of ten segments. At the stage of preliminary calculation stress-strain properties of supporting profiles vulcanizing press were determined by using SCAD software. Point load of hydraulic cylinders is transmitted on profiles in accordance with terms of reference. Strength calculation supporting profile in ANSYS software was carried out using Finite Element Method. The segment of the device under consideration is symmetrical with respect to two planes. Therefore, it was decided to simplify the calculation model using the capabilities of the ANSYS software, namely using the "Symmetry" modifier. This simplification reduces the requirements for computing power of the computer, which, in turn, allows to build a better mesh. Mesh is constructed mainly from eight-node volumetric elements of regular shape. Analysis of the supporting profile in ANSYS software confirmed the results of preliminary settlements. There are stresses in the dangerous sections of the upper profile exceeding the yield point. Despite this, during unloading, residual deformations in the profile are absent, since for the most part of the profile length in the sections there is no limiting state, that is, the stresses do not reach the yield point.
