Gearbox synchronizers. Behavior

The design of a mechanical system relies both on characterizing the behavior of the product architecture itself and on predicting the strength of each of its components. Many software programs, such as Finite Element Analysis (FEA), provide answers to the second question. On the other hand, the first aspect of architecture is often left to the discretion of the designer, who may have to take considerable risks if he or she does not have the means to quantify the overall behavior of the mechanical system concerned. Integrating a mechanical system into more complex assemblies requires a clear description of the respective behaviors. Naturally, the boundaries of the study areas must be well defined beforehand and the models must also be adapted. so that they can be translated into numerical results. Software environments now make it relatively easy to translate simple behavioral models. We can then obtain results from numerical simulations and carry out parametric studies.

This article sets out to study and develop gearbox synchronizers. The effects of gearbox architecture and synchronizer positioning will be discussed. Next, a study of the influence of key parameters will clarify the operation of Borg-Warner synchronizers.
