Beschreibung
Gear drives are key components for all kinds of machines as well as of industrial equipment.Therein, planetary gear systems, beveloid gears and cycloid gears are increasingly used in industry. Gaining more comprehensive understanding of those types of gears is essential. However, the measurement of the dynamic response of these gears is often not an option by virtue of the high cost of the required experiments, the calculation of the contact forces over numerical simulation is an important concern. Along with the development of computer technology, several numerical tools and methods to study gears with standard and nonstandard flank profiles have been introduced.
Simulation results from a detailed finite element model can be regarded as highly precise, but the numerical effort is usually too demanding, especially when a large system with many contacts and full rotational revolution of gear wheels is investigated. To overcome the large finite element integration times, a fully elastic multibody model using a modal description and an efficient contact algorithm is briefly presented. The proposed elastic multibody method with modal description allows very precise simulation of impacts between gear wheels for many gears, many revolutions and many contacts in comparably short time. In this work, the contact forces and contact behavior of planetary, beveloid and cycloid gears have been studied using the efficient elastic multibody system approach. Applying this approach, the strong and weak points of the gear types are clearly represented. It is well suited for simulations of technical relevance within reasonable time.
