The article discusses modern approaches to determining the main parameters of small-sized vibrating pads, which are widely used in the construction industry for compaction of concrete mixtures and the formation of products with specified physical and mechanical properties. The relevance of the study is due to the need to increase the efficiency of vibration equipment while reducing energy consumption, material consumption and dimensions of installations.
The main attention is paid to the analysis of existing methods for calculating the dynamic characteristics of vibration sites, in particular, the determination of the amplitude of vibrations, the frequency of excitation, accelerations of the working platform and the parameters of vibration exciters. Analytical, empirical and numerical approaches to modeling oscillatory processes, including the application of methods of the theory of oscillations and finite elements, are considered. It has been established that traditional analytical dependencies do not always take into account the influence of design features and real operating conditions, which can lead to deviations between the calculated and experimental data.
The paper conducts a comparative analysis of various calculation methods, identifies their advantages and limitations in terms of accuracy, labor intensity and the possibility of practical application. Particular attention is paid to the influence of the loading mass, the rigidity of elastic elements and the parameters of the excitatory force on the efficiency of the vibrating platform. It is shown that the most promising are combined approaches that combine analytical calculations with numerical modeling and experimental verification of results.
The results obtained can be used in the design and modernization of small-sized vibration units, as well as for optimizing their operating modes, taking into account specific technological conditions. The practical significance of the study is to improve the quality of compaction of concrete mixtures, reduce energy costs and ensure the reliability of equipment operation.
Thus, the analysis allows us to form reasonable recommendations for the choice of effective methods for calculating the parameters of small-sized vibration platforms and determines the directions of further scientific research in this area.
