Subject: DESIGN GUIDELINES FOR CHASSIS COMPONENTS (A.A. 2021/2022)
Unit Design guidelines for Chassis Components
To be chosen by the student (lesson)
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.
1) Tools & Methods
Decision Matrix Approach, V-shape development, Standard development plan for a car and for components, DVP&R and Statistics approach to validation, Main workflows in a car development
2) Suspension System
Variants used in automotive and decision matrix; Basic description of components, main forces to consider to size suspension elements, which mission profile for which car, evolutional trends for suspension
Active Suspension Components
Basic description and requirements, main parameters used to size, integration with Hi-Level control module for Ride & Comfort (shock absorbers and air springs)
3) Braking System
Braking system description, basic requirements for an automotive application, main parameters used to size brakes, modulation system, ADAS special requirements, brake-by-wire additional requirements
4) Steering System
Steering system description, basic requirements for an automotive application, main parameters used to size steering, EPS, AWS, ADAS special requirements, steer-by-wire future trends and additional requirements to understand
5) A Practical example
From Suspension Kinematic to Components CTS
Distance lessons and exercises These, and any exercises, will be recorded. Streaming sessions will be provided to answer questions on the program.
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.
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.
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.
Teacher's notes and presentations are sufficient for attending the course.
