Summary

 
Object and purpose of research.This paper studies a large welded sidewall structure manufactured at Sevmash. The purpose of the study is to determine vibroacoustic efficiency criteria for low-frequency vibration treatment
Subject matter and methodsDynamic parameters of the sidewall were studied by exciting it by impact during its lowfrequency treatment, an intermediate operation prior to mechanical processing
Main results.This work identified vibroacoustic efficiency criteria for low-frequency vibration treatment of welded sidewall structures.
Conclusion.This work shows that monitoring of amplitude-frequency parameters could be applied in assessment of efficiency (sufficiency) for low-frequency treatment.
