The use of dynamic modeling for optimization of machine design on the example of a toothed gear

The paper presents a dynamic model of a test stand with gears operating in a circulating power system as an example of the possibility of using dynamic modeling to optimize the gear construction. The presented model is one of two advanced tools developed within the research conducted for the optimization and diagnosis of various types of gear transmission systems. Both of them were based on the assumption that simulations of system operation at variable loads and rotational speeds could be carried out and that an advanced description of gear tooth interaction could be included. The developed models, after their tuning to real objects, were used as tools for generating vibration signals for various technical states of gears. This allowed determining the influence of various constructional, technological, and operational factors on the vibroactivity of a toothed gear, which is undoubtedly helpful for designers both during the construction of new toothed gears, as well as optimization of the existing ones.
