This paper describes a test stand along with a model of a lance used in glass works. A prototype friction damper was used for vibration damping of the lance. Experimental tests were conducted, whose aim was to determine operating conditions under which the damper will be the most effective. Damping was evaluated based on the damping decrement determined using the resonance curve for the first form of vibration of the lance. It was found that a friction damper has optimal values of preload force from the point of view of damping of the lance's resonant vibration.
The design method how to increase the reliability of the railroad underframe frictional dampers has been given. The new design for frictional wedge has been suggested, it helps to decrease both the wear of friction wedge and the deterioration of the connected with shpinton sleeve.

Explained are problems occurring during the glass working robot production cycle. Construction, operating principle and control range of the glass working robot frictional damper are presented. Also, numeric modeling options of the frictional damper are explained. Consequently, MSC ADAMS software pack was used to create model of a frictional damper basing on which, vulnerability of numerical model in application to selected solution of the frictional damper was presented.
The design of the main friction pair of the frictional oscillations damper of passenger car axle box stage suspension and its manufacturing techniques are described. The difference of the design of the main friction pair consists in replacement of a conical contact surface of the shpinton sleeve by a pyramidal surface as well as a cylindrical surface of the frictional slide block by a flat surface of the rectangular form. Technological ways of increase of strength and wear resistance were developed that allowed quantitatively to estimate a reserve of increase of strength and thermal wear resistance by methods of plastic deforming. With the purpose of increase of wear resistance and resource saving the new technology of producing the shpinton sleeve blank is offered by a method of cold die forging, and a frictional slide block - by hot die forging.
