Overview

The course aims to provide insight into the components that make up the chassis of a modern vehicle.
The main technical characteristics of the components analyzed and the performance they must guarantee on the car will be outlined. The main "good engineering" rules that must be respected for correct installation and to guarantee the desired performance will be described.
The main challenges related to the new technological trends in the automotive sector will also be exposed regarding the components of the Chassis perimeter.

Teaching methods

Distance lessons and exercises These, and any exercises, will be recorded. Streaming sessions will be provided to answer questions on the program.

Assessment methods

The exam consists of a Q&A session based on five questions. They can be: component sizing exercises and / or open-ended theoretical questions. The use of books or notes is not allowed during the test.

Learning outcomes

Technical knowledge
Application level knowledge and ability to understand the methods, the fundamental lines of the development of industrial products / processes in the automotive world, the collection of information and the sharing of possible technical solutions to problems of daily relevance in a technical office of an OEM or an automotive supplier.

Autonomy of judgment
Through the comparison with the teachers, the student develops the ability to understand, critically discuss and present their ideas to solve an engineering problem related to the development and installation of components of the chassis of a modern vehicle.

Communication skills
Through the comparison with the teachers, the student develops the ability to communicate technical information, ideas, problems, technological solutions, to specialist and non-specialist interlocutors, through the graphic engineering language, technical documents and prototypes.

Ability to learn
The student develops the learning skills necessary to deepen technical topics independently, in order to effectively deal with the insertion into the world of work, to undertake subsequent studies or to update themselves on innovative methodologies and technologies through technical literature.
