Service-life prediction of newly-designed brake gears having in consideration innovation engineering concepts

Specific rational problems were brought to consideration in order to validate design parameters and characteristics, particularly behavior of brake systems and their components, for gaining maximum performance of forestry vehicles, thereby providing safe operation and maximum output efficiency of the machinery concerned. The experimental study results have been generalized to improve efficiency of transport-processing vehicle brake systems for predicting service life of newly designed brake gears having in consideration innovation engineering concepts subject to the invention. According to the invention “Method of compressed air circulation with air fed to the brake gear friction surfaces during braking and its embodiment”, it is offered to provide air circulation in the wheel brake gear during braking so that air is charged to the brake gear friction surfaces with a brake gear block and drum moving close to each other. Some complex experimental studies were held in order to identify possible positive effects for implementing such technical decision. The experimental study results were analyzed for demonstrating improvement of forestry vehicle brake performance. The heuristic approach was offered for solving the problem generalized in order to improve forestry vehicle brake performance. The first similarity theorem was applied as a working hypothesis. Taking into account the previously offered theories of similarity of brake block behavior when testing on a bench and on a virtual loader, it was possible to predict service life of the brake gear subject to the above technical decision. As a result, the method of service life prediction of newly-designed brake gears having in consideration innovation engineering concepts subject to the invention was provided.
