Certification
In 2001 the quality management system of SPC Dynamics was put through facultative certification. In 2016 it was recertified for compliance with standards ISO 9001:2008. Its results confirmed a high level of goods and services quality management. In 2001 the quality management system of SPC Dynamics was put through facultative certification.

Research on vibration activity of assemblies in rail-tracked rolling stock’s mechanical parts

Print

In terms of an operational process of rail-tracked rolling stock, the most important assemblies, liable to sudden failures, are limiting the rolling stock in general.  Such assemblies include ones of electric and mechanical equipment which failures cannot be eliminated during operation.

The most efficient methods of detecting failures of rotary mechanical equipment is heating and vibration-acoustics, however, heating method allows barely state the fact of beginning of an assembly’s destruction, or find defects on a late stage of their development, as long as the vibration-acoustic method of NDT allows to detect both nucleating and developed defects.

Big amount of interferences and high noise level accompanying interaction of a wheel and a rail track has formed a common opinion on provision objective vibration acoustic condition diagnostics of rolling stock’s rotary machinery condition in operation being hard or, sometimes, impossible to achieve.

The research is aimed at providing the most informative, in terms of vibration-acoustic diagnostics, frequency range of a vibration signal, in order to develop an expert system and provide condition monitoring of a rail-tracked rolling stock.
