Experimental Research of Vibrational Properties of a Single-Axle Trailer when Crossing an Individual Road Obstacle

Investigation of road vehicles in term of their dynamics is very important task. There are assessed two main points of view, i.e. the driving safety and ride comfort for passenger. This article is aimed at analysis of dynamics of a single-axle trailer by means of real tests. Several driving manoeuvres have been performed and evaluated, at which, when a trailer has been towed by a passenger car. As the main output parameters, acceleration signals have been measured and recorded. The vehicle-trailer combination has been moved at several driving speeds.
