摘要

In this article, the mathematical model of the modernized shock-vibration mechanism for compaction of bulk materials is considered (including those that are difficult to deform) based on a four-link mechanism, which includes the Archimedes lever. The article shows the advantages of this mechanism relative to the previous one. Displays formulas for calculating drive increase factors. The mathematical model of the mechanism consisting of geometrical, kinematic and power calculations is described. Based on the mathematical model, the necessary conditions for the successful operation of this mechanism were selected. The department “Wheeled and Tracked Vehicles” of SUSU designed a 3D-model of the working body based on a four-link mechanism and the entire pilot plant. Thanks to a specially designed bearing surface frames (table) that allows you to adjust the height of the seal from 10 to 250 mm. After the installation is completed, it will allow not only testing the four-link mechanism, but also to understand how deep and with what effect it is able to compact. By conducting early tests on a shock-vibration stand with a hinged-lever mechanism with a compaction height of 65 mm, the technological capabilities and advantages of this mechanism were confirmed in comparison with the vibration compaction technology adopted on modern wheeled or tracked concrete pavers, namely, control samples of concrete showed an increase strength 1,2-1,4 times in comparison with the strength of the samples obtained by traditional sealing technology. But the relative disadvantages of such a design were also found, which were eliminated in the modernized shock-vibration mechanism based on the four-link mechanism.
