Abstract

The rocking motion of two-wheeled suitcases is investigated. A rigid body mechanical model of the suitcase is constructed. All of the possible motion states (both wheels on the ground, one wheel on the ground, none of the wheels on the ground) are taken into account. The switching between the motion states is accomplished by a simple impact model. The motion of the suitcase is investigated through numerical simulations, furthermore the domain of the attraction of the stable rectilinear motion is identified. The model is partly validated by experiments.
