VibroAcoustical Systems and Technologies, Inc. was established by specialists
who have great experience in vibrodiagnostics. They started their investigation
of the vibrations of electric mechanisms in 1968. The main aim of this team was
to determine the reasons for increased vibrations in electric mechanisms on
board ships and to develop methods for decreasing these vibrations.
There are very strict regulations concerning the vibration of the machines and
mechanisms on special ships in Russia. If the vibration level increase, naval
personnel are required to carry out detailed investigations of the reasons for
the increases and determine the means for dealing with the vibration increase.
Before 1975-76, our specialists were responsible for teaching the personnel and
developing special methods of vibration investigation.
We were responsible for electric machines, fans, pumps, and propellers. We also
performed diagnostics of gearboxes, turbines, and compressors. Our main tasks
were to develop methods of diagnostics this machinery using a tape recorder and
standard spectrum analyzers and teaching the personnel of special diagnostic
teams in naval bases. The first methods standard was issued in 1980 and included
new vibration methods such as envelope detection, pseudo-vibration etc. After
testing, a new, improved, standard method for ships was issued in 1983. Since
then, it’s being used, not only on ships, but also on a number of large plants.
In 1986, a book devoted to these methods of vibrodiagnostics was published.
For more than 10 years ( 1980-90 ), we have collected a large quantity of
statistics on vibrations of electric mechanisms. In 1987, our specialists were
able to make extremely reliable diagnostics on ship mechanisms. At that time, we
started to widen applications of our methods, particularly in electric machinery
building plants, paper industry, etc.
Since 1988, due to conversion of the Russian economy, we have had the
opportunity of looking for new customers in other industries.
In 1990, a small state enterprise “VIBROTECHNIQUE“ was created. At that time, we
started a project of developing automatic systems for fast and reliable
diagnostics of a large number of rolling element bearings in machines. This
system does not need a highly qualified operator.
In 1992 we founded a joined share company named VibroAcoustical Systems and
Technologies, (VAST, Inc.) that deals with the development and the supply of the
multipurpose diagnostic systems and rotor balancing complexes.
