Detailed
description of topics:
Basic elements of the dynamics of road vehicles
(car, truck, motorcycle). Ride vibration response to road unevenness. Sine and stochastic
roadprofile. Single, two and three mass/spring/damper systems. Linear and non-linear
models. Vibrational modes and stability. Discomfort analysis. System identification.
Roadholding: vehicle handling and stability. Response to stear input and side wind. Singel
two-wheel vehicle model to discuss effects of tyres, inertia and geometry. Influence of
several design variables: steering and wheel suspension, kinematics and compliance, toe
angle, camber, roll axis, roll stabilizer, load transfer. Motorcycle stability and modal
shapes (brief discussion of results)
