Summary

 
Object and purpose of research. This paper studies vibroacoustic parameters of ship equipment in different operational conditions. The purpose is to develop vibrodiagnostic models of marine equipment and find threshold values for diagnostic parameters to be used in vibration-based monitoring.
Subject matter and methods.The study relies on experimental and statistical research methods. Diagnostic models were constructed as per random process theory and based on the available statistics of failures and faults with ship machinery
Main results. Development of vibration-based method for determination of technical condition of ship machinery and determination of spectrum masks for assessment of its current operational conditions. The method was evaluated at the experimental sample of DRK-2500 pod propulsion unit at the test rig of the manufacturer (the town of Severodvinsk).
Conclusion. Mathematical models suggested in this work for monitoring of operational modes and technical conditions of marine equipment working in harsh environments have been successfully developed and tested. This method will enhance operational safety and reliability of ice-class ships.
