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)
