Contribution à la modélisation multi-physique : électro-vibro-acoustique et aérothermique de machines de traction

Abstract : Transports have been developed for the past few years. This major development has been followed by growing concern for the respect of environment. Although railway transports present high energy efficiency, they also present environmental injuries. It is then necessary to include the sustainable development from the moment of conception. It results in the consideration of numerous physical phenomena. Consequently, this PhD Thesis aims at emphasizing a conception methodology in the respect to the current will of economic and ecological optimisation. Then, a multi-physical model has been developed in order to represent electromagnetic, acoustic and thermal-flow phenomena in an enclosed induction motor of railway traction. In fact, this model is divided into several analytical interacting models. Each model represents a specific physical phenomenon. This work focuses on the thermal-flow model and the losses model, and in particular on the modelling of the iron losses. Although these models are analytical models, they both rely on numerical studies. The multi-physical model has shown to be efficient and to respect the main evolution trends thanks to comparison with experimental results and analysis of the uncertainties influence.
