The paper shows a possibility of the tuning mechanical system by means of two pneumatic springs in a differential configuration connected with a throttle valve. The springs are inserted into the lead mechanism and connected to its parts, and to its supporting platform. The vibrations, transferred from the kinematic excitation of the base, are inten...

Since material losses of many engineering materials are known to be independent on frequency, the viscous damping is not always appropriate model of damping. In the case of structures, the effect of damping is usually small far from the system resonance. Unlike the case of structures, the material damping of rotor can lead to system instability. Tr...

The spring suspension of an ambulance couch has three degrees of freedom. Its guide spacious mechanisms is parallelogram for vertical suspension; on the upper base of which is a double Cardan suspension with horizontal axes. The vibroisolation is realized by pneumatic springs with a position control. So that all proper frequencies might be lower th...

Hard and tribological coatings are very frequently used as wear protection on variety of steel parts in many applications, e. g. cutting tools, movable parts. Applications of hard coatings on soft substrates are accompanied by difficulties with perforation of coatings when load overcomes some critical value. Our research was aimed on investigation...
