Linear Dynamic Analysis of Continuous Sections of Vibrating Machines

Goal. It consists of studying the influence of the frequency of harmonic disturbance of a continuous section in the form of a rectangular plate on its maximum stresses, deflections, and acceleration, and in identifying frequency ranges in which there is a significant amplification of the oscillations of continuous sections. Significance. In known designs of discrete-continuous vibrating machines, only the first natural frequency of oscillations of the continuous section is used to implement energy-efficient modes of operation.

DETERMINING THE INFLUENCE OF CONTINUOUS SECTION SHAPE AND DIMENSIONS ON STRESSES OVER A WIDE RANGE OF VIBRATION FREQUENCY

Problem statement. Considering the prospects of using discrete-continuous vibration machines, there is a need to study the properties of continuous sections, which are elastic plates, in a wide range of frequencies. Purpose. It consists of studying the frequency response of continuous sections of various shapes and sizes from the harmonic disturbance force and identifying the frequency ranges in which the maximum stresses will be observed. Methodology. A schematic diagram of a discrete-continuous oscillating system is given.

OPTIMIZATION OF THE SHAPE AND DIMENSIONS OF THE CONTINUOUS SECTION OF THE DISCRETE-CONTINUOUS INTER-RESONANCE VIBRATING TABLE

Energy-efficient technologies are an important aspect of the development of mechanical engineering. Therefore, the creation of highly efficient vibration technological equipment is an urgent task. There are discrete-continuous inter-resonance vibration machines that have high values of dynamic amplification of oscillations. Rectangular plates or rods are used as the reactive mass of such vibrating machines. However, the rectangular shape of the plate may not be the optimal shape for achieving maximum energy efficiency.
