Subject fundamentals
The module teaches the basics in designing a chassis. Special attention is given to the functions, more common architectural and construction solutions and implementing the modelling of its effects on vehicle dynamics. Active control systems for vehicle dynamics and related control strategies are also examined. The mathematical models allowing to study the dynamics of road accidents are also dealt with.
Owing to the importance of the aerodynamics of the vehicle on its dynamic behaviour, a part of the course will be devoted to the study of the interaction between the vehicle and the atmosphere.
Expected learning outcomes
Students learn to how to design a chassis and focus in particular on suspension, steering and braking subsystems. thus they must be able to recognise and differentiate the main architectural possiblities, to organise models for simulation and understand the advantages to be gained from using active control systems.
Prerequisites / Assumed knowledge
It is necessary to be familiar with the topics covered in the Techniques for Modelling and numerical simulation model.
Contents
1 - Introduction
Using CAD systems, models and simulators for design
FEM and multi-body analysis - functional and structural
2. Vehicle modeling
Various modeling approaches
Synthetic models: non-linear, linearized, semi-linearized.
Vibration analysis of a complete driveline
Analysis of the handling behavior and the stability of a vehicle on the road
Interaction between driver and vehicle
Effects of body compliance on handling
3. Active control of vehicle dynamics
Vehicle driver interaction: linerarized models

Active handling control and control of the stability and of the rolling motions (ESP, ARC)
Active comfort control: active suspensions
4. Road accident dynamics
Simplified models for accident reconstruction
Extension of the dynamic vehicle models to the motions occurring during accidents
Delivery modes
Students are required to carry out practical work on the following:
Gradual implementation of a vehicle model using multibody codes and simulation when design parameters are changed.
Numerical simulation of the control system and checking performance
Reconstruction of a car accident
