Abstract: The first cars in the history were purely mechanical devices and were designed based on the model of carriages drawn by horses. Since then, automobiles are much developed and represent a marvel of complex interdisciplinary engineering. Indeed, automakers have more and more integrated new technologies in vehicles to meet customer needs. Among these new technologies, there are hybrid vehicles that were developed to overcome the problems of the environment’s pollution and to avoid energy crises. In this work, one type of hybrid vehicle was focused on, which is the electric hybrid vehicle with two-wheel drive. Various subsystems of this vehicle is presented and its dynamic model is developed using AMESim software. The operating New European Driving Cycle (NEDC) is used to compare our simulation results and to optimize the functioning of the system.

Abstract: The aim of my current research is to improve the acoustic performance of a sandwich plate with corrugated core. It finds application in high speed trains and aircraft, where a major concern for the comfort of passengers is the low frequency noise, especially after the ineffectiveness methods of geometric optimization and passive control. Active control by means of PZT patch is the approach my research will follow. When the dynamics of the structure is studied, the boundary conditions (BC) play an important role: they influence natural frequencies and mode shapes, and the way the active control should be implemented. In this paper I show my results on the vibroacoustics performance of the sandwich structure, together with the influence of BC on the actuator placement.
