Experimental Studies of Steady-State Sources of Vibrations of Machinery Production Process Equipment to Substantiate Choice of Vibration Protection Methods
Abstract
Vibration is one of the factors accompanying virtually every production process and largely characterizing its quality in terms of its impact on the environment and humans. The adverse effects of industrial vibrations predetermine a set of measures to reduce vibration. These measures are taken by the developers of structures and technologies, as well as experts in the field of occupational safety and labor comfort and environmental protection. The main sources of industrial vibration are considered here. The main factors contributing to the formation of mechanical oscillations in the components of process equipment kinematic chains are vibration effects, including steady-state, nonsteady, random effects. The experimental studies of steady-state sources of the formation of production vibration were carried out. The aim of the study was to determine the relationship between the change in the level of imbalance and the vibration level in frequencies ranging. The reason for the imbalance of rotating parts is the displacement of the center of mass relative to the axis of rotation. The results of the experimental study of determining the relationship between the change in the level of the imbalance and vibration level in frequencies ranging are presented.
