About Barbour Stockwell Incorporated
|
Barbour Stockwell was founded in 1858 and throughout its history has been involved in the
design, development, and manufacture of special machinery for unusual applications.
In keeping with this tradition, BSi began building high speed spin test turbines for the General
Electric Company at the dawn of the jet age.
In the early 1950's the company began to devote its entire capabilities to the development and
application engineering of high speed drives and control systems.
Today, from our 20,000 ft2 facility in Woburn, Massachusetts, the company continues
this work. Our unsurpassed ability to generate and precisely control high speed shaft power is
the key advantage in our spin test facilities and test benches.
All the leading producers of rotating machinery and related components as well as
government and university laboratories use our products throughout the world.
Many of the facilities we have built have incorporated environmental control systems.
We have provided such systems to generate temperatures from 80 Kelvin to 1,100°C.
The cryogenic system was part of a complete spin test facility for testing NASA Space Shuttle
Main Engine Rotors.
In addition to the design and fabrication of test facilities, the company offers test
services at its fully equipped lab in Woburn. The lab includes three fully automated spin
test facilities with a variety of drives for achieving speeds to 200,000 rpm and capacities
to 1800 kg.
Support equipment includes two computerized balancing machines with fixturing to precisely balance
work pieces from grams to 275 kg. High speed photography of rotor bursts is performed
routinely. In addition, the capability exists for heating test specimens to 800°C.
The existence of an in house facility not only allows us to offer high speed test services
to organizations that cannot justify their own equipment, but also gives us the means to
develop and fully test improvements in our products. Moreover, we have developed considerable
expertise in the design of tooling for stable spin testing; a service which we offer to our
customers.
Software employed at BSi includes Dyrobes for rotordynamic analyses and NASTRAN for FEA.
To augment our library of purchased engineering software, any frequently performed calculations
are programmed by us to save time and eliminate error. Our new designs, including layouts
and manufacturing drawings, are performed using AutoCad and/or Solidworks.
The company maintains a shop at its facility in Woburn for machining and welding parts.
In addition, the company has a network of skilled vendors to meet virtually any fabrication
requirement. Irrespective of source, quality assurance is maintained by BSi.
