Abstract
Many procedures for gear strength analysis are available today, however only the classical procedures based on DIN, AGMA, ISO, etc. standards are most commonly used in gear design. These procedures and standards are usually based on the results of experimental measurements conducted on reference gears and a number of influiential parameters that account for actual operational conditions. However, the influential factors in mentioned standards are not formulated accurately enough and are still a subject to many research investigations. Also, the classical procedures are solely based on the transformation of a gear, which is in essence a three-dimensional element, into a plane problem. The fundamental aim of the proposed research project it to develop a completely new procedure for gear strength analysis, which would be based on 3-dimensional computational simulations that allow for simulation of actual operating conditions on gears. The new modell will enable monitoring of a gear condition starting from the very first loading cycle until the damage appearance and with that more reliable predicition of gear service life. For this purpose the existing and newly developed fracture mechanics theories will be used, which will provide for simulation of initial cracks, appearing in gear tooth root or tooth surfaces, and its growth until fatal damage renders gears unoperational. To fullfill the set aim it is envisaged that the model will comprise the knowledge from different scientific fields, such as mechanical elements, materials, contact problems, tribology, fracture mechanics, computational methods and probability theories.
