The article examines and studies vibration equipment used for vibroforming concrete products with the application of elastic rubber vibration mounts. The relevance of this topic is confirmed by the widespread use of such equipment by industrial enterprises in the production of small-sized concrete products for paving streets and public areas.
The aim of this work was to investigate the effect of the temperature of rubber vibration mounts on the amplitude of vertical oscillations of a vibrating table, maintaining the required value of which has a decisive impact on the quality of the manufactured products. General empirical and theoretical research methods were employed in the study.
Initially, various designs of rubber vibration mounts used in vibroforming equipment were analyzed, with an assessment of their structural and operational features. Subsequently, experimental studies were carried out on operating vibration equipment to determine the temperature regimes of rubber vibration mounts and to measure the amplitude of vertical oscillations of the working element.
The research revealed that at the initial stage the oscillation amplitude has minimal values; however, as the temperature increases, rubber loses stiffness due to increased mobility of macromolecules and a decrease in the modulus of elasticity, which leads to a gradual increase in amplitude. A detailed analysis of the experimental results was conducted to evaluate the influence of the studied parameters on the efficiency of the equipment operation.
Practical recommendations for the operation and improvement of vibroforming equipment with elastic rubber vibration mounts are provided, taking into account the obtained results.
