Overview

Understanding of fundamentals of vehicle dynamics, consisting of basic models and analytical – computational tools.

Admission requirements

Vibration mechanics.

Course contents

Kinematic steering (Ackermann condition).
Longitudinal dynamics (acceleration; braking).
Power transmissions (gears; differentials).
Suspension mechanisms (kinematics; equivalent stiffness and damping).
Tyres (kinematics; tire slips; longitudinal and lateral forces; aligning torque; camber thrust; brush model; relaxation length; semi-empirical formulas).
Lateral dynamics (planar double track and single track models; steady-state cornering; steering pad; effect of side forces; handling diagram analysis; understeer gradient; stability analysis).
Vertical dynamics (linearized models; quarter car model; ride and comfort analysis; tuning of suspension springs and shock absorbers).

Teaching methods

Lectures by staff, technical seminars by specialists from automotive industry, computer exercises.

Assessment methods

Oral examination.

Learning outcomes

Learning of basic methods and techniques of vehicle dynamics, developing the skills necessary to autonomously deepen technical topics, in order to effectively face professional challenges or to undertake further studies.
