Abstract
A schematic diagram of the shock-vibration for compacting materials (including hard-to-deform) and the principle of its action based on the lever of Archimedes, which is part of a four-link mechanism, is considered. The article shows the expression for calculating the gain mechanism of the compression mechanism. In the course of work, a mathematical model of the mechanism is described; formulas for the kinematic and force calculation of all links of the mechanism are derived. With the help of the derived mathematical model, it is possible to select the most optimal options for the sizes of links according to the force or dimensional characteristics. The necessary conditions for a successful operation of the new mechanism are described. Its 3D model and general view of the pilot plant, which was designed and installed at SUSU at the Wheeled and Tracked Vehicles department, are shown. According to the tests carried out on it, the technological capabilities and advantages of this mechanism were confirmed in comparison with the vibration compaction technology adopted on modern wheeled or crawler concrete pavers, namely concrete control samples obtained on a molding machine with a shock-vibration mechanism showed an increase in strength of 1.3–1.5 times in comparison with the strength of the samples obtained by a traditional sealing technology.
