The relation between unevenness, its description and vehicle vibration response with regard to roll of the wheel on track will be comprehensively addressed.

Currently used road unevenness indicators will be mutually compared.

The sensitivity and possibility to reflect the quality of road surface for different random profiles combined with controlled parameters of impulse components will be evaluated.

The correlation between road unevenness and vehicle vibration response will be assessed.

The suitability of unevenness indicators to reflect ride comfort, ride safety and vehicle and road dynamic loading will be evaluated.

The possibility of reducing the vibration of auxiliary machinery located on the vehicle frame by semi-active actuators will be analysed.

A test stand with electro-magnetic actuator will be constructed and its vibro-isolation effect will be evaluated.
