Unit Vehicle Dynamics
Mechanical Engineering (lesson)
Understanding of fundamentals of vehicle dynamics, consisting of basic models and analytical – computational tools.
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).
Lectures by staff, technical seminars by specialists from automotive industry, computer exercises.
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.
