Abstract

This master's thesis focuses on the application of the Finite Element Method (FEM) for analysing gears with microgeometric modifications. Its aim is to investigate how these modifications influence gear behaviour under various loading conditions. Additionally, the thesis explores the utilization of commonly available computational software for performing FEM analyses of gears, potentially offering economic and time-saving benefits compared to specialized software solutions. The first part of the thesis addresses the issue of microgeometric modifications. It outlines types of gear errors, the significance of these modifications, their manufacturing process, and basic modification types. The subsequent section of the thesis discusses the design of an accurate 3D model of involute gearing according to the ČSN standard using appropriate software. Microgeometric modification of the gear is applied on this model. The created 3D model of the modified gear is then exported to the ANSYS Workbench environment, where a structural FEM analysis is conducted for a specified duration of operation. The results of these analyses are presented using contact and pressure patterns and are compared for various loading conditions. The entire process of creating the 3D model of the modified gear, exporting it to the ANSYS Workbench environment, configuring the FEM analysis, and evaluating the analysis results is thoroughly and systematically described within this master's thesis. Thus, the thesis can serve as a guide for analysing modified gears using FEM analysis techniques.
