ANALYSIS OF PARAMETERS OF VIBRATIONAL PROCESSES OF THE CARRYING FRAMEWORK OF THE INDUSTRIAL BUILDING

Abstract

The paper presents the results of studies of the parameters of the oscillatory processes of the structural structures of the bearing frame of the building of the preparatory department of the plant "Bunge CIS" in the village. Well of the Voronezh region. The approaches to the solution of the problem of excessive vibrations of elements of a bearing metal frame are described. The data of the recorded measurements at the facility with special instruments - Vibran 2.2 and a multichannel measuring system - are analyzed. The technique of measurements, the scheme of arrangement of acceleration sensors is described. The frequencies of oscillations are estimated, the results of spectral analysis are presented. The main causes of excessive vibrations of the frame elements of the building are identified and the types of equipment that have the maximum influence on the vibration of building structures at the facility are established. Numerical static and dynamic calculations are performed, the bearing capacity is estimated using an original technique based on the surfaces of the relative resistance, and recommendations are given for reducing the production vibration.
