Key Research Results and Achievements
Scientific bases of calculation and design of shock machines based on mechanisms of variable structure with kinematic decoupling of impact node at the moment of impact have been developed.
A dynamic model of the transmission of a percussion machine with a variable structure mechanism has been developed.

Design and manufacture of prototypes of hand hammers based on two-creepy creep mechanisms of variable structure.
Development of methods for calculating and designing a centrifugal shock crusher of dynamic action.
Development of a generalized mathematical model of a jackhammer with a splitting slider with an air cushion.
Distinctive features and kinematic properties of three varieties of schemes of mechanisms of variable structure with the largest base are revealed.
The regularities of changes in kinematic parameters depending on the coefficient of the largest link in the range a [2 20] are established.
The dependence of changes in the magnitudes of reaction forces in kinematic pairs and supports of the links of the impact mechanism on the coefficient of the largest link a is obtained.
The dependence of the most important operational characteristics of the shock mechanisms, such as energy and frequency of impacts, shock power, on parameter a, which allows to increase the performance of the machine, has been established.
Recommendations have been developed for the implementation of these schemes for the creation of shock machines for various purposes.
Schemes with rational kinematic and force parameters have been identified and recommended for creating shock machines for specific areas of their application: for soil compaction, for cleaning surfaces, for seismic sensing of the earth’s crust.
An experimental sample of a portable impactor model M10-19 with a drive from an asynchronous electric drive was developed.
The dynamics of the percussion machine with the help of a high-speed video camera is studied.
Schemes for creating sealing machines based on the mechanisms of the variable structure C are identified and recommended. Abdraimova.
