The course aims to provide a vision of the components that make up the chassis of a modern vehicle.
The main technical characteristics of the analyzed components and the performances that they must guarantee on the vehicle will be outlined. The main rules of "good engineering" 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 with regard to the components of the Chassis perimeter.
1) Tools and methods
Decision matrix approach, V-shape development, standard development plan for a car and for components, DVP&R and statistical approach to validation, main workflows in car development
2) Suspension system
Variants used in the automotive sector and decision matrix; Basic description of components, main forces to consider for sizing suspension elements, which mission profile for which car, evolutionary trends for suspensions
Active suspension components
Basic description and requirements, main parameters used for sizing, integration with High-Level control module for Ride & Comfort (shock absorbers and air springs)
3) Braking system
Description of the braking system, basic requirements for an automotive application, main parameters used for sizing brakes, modulation system, special ADAS requirements, additional brake-by-wire requirements
4) Steering system
Description of the steering system, basic requirements for an automotive application, main parameters used for sizing steering, special requirements EPS, AWS, ADAS, future steering trends and additional requirements to understand
5) Functional Safety Analysis
Brief description of the objectives of this type of methodology and application for the design of electromechanical components of the Chassis area.
6) A practical example
From suspension kinematics to component specification (CTS)
