Passive tuned mass dampers (TMD) of various types are widely used in civil engineering. TV towers, masts and other slender structures exposed to wind excitation are usually equipped with such devices. If there is an insufficient place to install a conventional pendulum type device, an absorber of the ball type represents a convenient solution. In the paper, the response of a heavy ball rolling inside a semi-spherical cavity under horizontal kinematic excitation is analyzed. The system with six degrees of freedom with three non-holonomic constraints is considered
