Riassunto analitico
This thesis is the final work of the Master’s Degree in Advanced Automotive Engineering delivered by the Motorvehicle University of Emilia Romagna (MUNER). The curriculum High Performance Car Design focuses on every aspect of the vehicle, apart from the propulsion system. In this wide framework, I got passionate about NVH (noise, vibration and harshness) and I decided to do my curricular internship on it.
The company where it took place is Toyota Motor Europe. Here I was assigned the task of studying the phenomenon of road noise. The focus is mainly on tire and suspension, plus an activity on rims.
First, a brief description of Toyota will be presented.
Then, the road noise problem will be introduced, and its generation and propagation mechanisms will be discussed.
Afterwards, the activities executed during the internship will be described. The investigation of tire performance is the first topic. It will start with the collection of the data needed to perform the study. They will be put in correlation up to obtaining relevant conclusions and KPIs (key performance indicators).
The second study covers the improvement of the CAE (computer-aided engineering) model of a suspension. With the goal of predicting performance virtually, it has been correlated with data obtained from tests and then tuned via an optimization process.
