Models and approaches in design and diagnostics of vehicles planetary transmissions

Abstract

The paper presents author's models and method for vehicle planetary transmission, which cover the stages of synthesis, kinematic, quasi-static and dynamic computations, dependability prediction and diagnostics of transmissions in operation process. The obtained data of the synthesis stage (block and kinematic diagrams, gear ratios of transmission mechanisms) are expanded at subsequent design stages with the ultimate goal of forming a complete information model (digital twin), allowing to support transmission design process and predict the behaviour of the transmission in operation. The emphasis is made on the developed original methods solving the most science intensive problems in the transmission life cycle.
