 Victor
Glodov, PhD ME
I have got MSME (Dynamics
and Durability of Machinery) from Polytechnic University of
Kharkov, Ukraine, (1968 -1974). My master’s thesis was
in modeling the transient torsion oscillations of tractor’s
transmissions. I’ve started my industrial vibration
engineering since 1974, working in Design Company of Tractor
plant, Kishinev, Moldova.
My main Work Experience in vibration area I
have got working in “Typhoon” Research & Design
Company, 1978-2001, Nikolaev, Ukraine. It was a great company
dedicated to research, design, manufacture and provide the
former USSR’s fleet and NAVY with axial/centrifugal
fans and air-conditionings any type. There were Aerodynamic
& Vibration/acoustics Laboratory (Bruel & Kjaer company
instrumentation), Shock-Test, HALT, HASS Laboratories and
variety another types of laboratories and departments, experimental
and manufacturing shops where I could design, manufacture
and experiment any ideas to resolve the customer problems.
Working in the Vibration/Acoustic Department as an engineer
and later as a Senior Scientist I supplied the designers along
all stages of the design and testing with recommendations
to provide with stringent requirements on vibration/acoustic
characteristics of fans and air-conditionings for NAVY.
My PhD ME thesis (Polytechnic University, Kharkov,
Ukraine, 1986) was devoted to the problem in reducing the
3-D vibrations of the reciprocating compressors for NAVY’s
air-conditionings: computing predominant exciting forces;
setting up precision dynamic balancing its crankshafts with
bob-weights; reducing vibrations from gas-dynamic forces and
principally non-balanced forces using dynamic absorbers; setting
vibration isolators in vibration’s nodes of compressor’s
housing. The results were applied in technical documentation.
I published 7 scientific articles and have 1 patent on the
results of my work:

I designed, manufactured and tested extremely
effective the ring-type, mushroom-type, flat-spring type,
spiral-spring type of dynamic vibration absorbers to eliminate
electro-magnetic, unbalance and gas-dynamic vibrations of
a machines, such as fans, superchargers, pumps, rotating/reciprocating
compressors, Diesel-generators, Diesel-compressors, etc.
I have hands-on experience in precision on-site
dynamic balancing of equipment using portable instruments
and shop balancing rotors using soft/hard-bearing balancing
machines, laser pulley/shaft alignment, resonance testing
and eliminating. I have knowledge and ability in diagnosis
of coupling and alignment errors in machine trains, identifying
damage in rolling-element bearings from the BEARCON Signature
Analysis and fault identification using Frequency Analysis.
Working in Research Company I performed training of engineers
and technicians on precision on-site dynamic balancing of
fans and shop balancing of compressors crankshafts with balancing
machines.
I performed computer modeling, designed and
would like to suggest to customers several know-how variants
(up to 10) extremely effective wide-band vibration isolation
systems including upper isolators, certain intermediate mass
with build-in linear/non-linear 3-D dynamic absorbers (mushroom-type,
ring-type absorbers, etc) tuned at the main harmonic frequency
and lower isolators attached to foundation. Small overall
dimensions, masses! Double effect takes place - dynamic absorbers
reduce 3-D vibration of an intermediate mass and supporting
structure at the main harmonic, others harmonics are significantly
reduced with intermediate mass. This revolutionary type of
vibration isolation systems is far more efficient compared
to conventional isolators with the same spring rate and could
be applied for ships, subs and industrial equipment to protect
the supporting structures from vibrations.
Since Aug. 2002 till Feb. 2003 I worked in RPM-Services Co.
in Brooklyn, NY as a Specialist in Data Acquisition, Dynamic
Balancing, Alignment, Resonance Testing/ Eliminating.
Since Feb. 2004 I work in American Ship Repair
Company, Inc. in Brooklyn, NY where I am in charge of setting
up dynamic balancing procedure for marine pumps rotating systems
using balancing machines and provide vibration tests.
I am a member of the Vibration Institute

and participate in its Discussion Zone.
