Mechanical Solutions, Inc. (MSI) provides new equipment design, computer-aided analysis, installed equipment field testing and problem solutions. MSI staff performs these tasks for all types of Pumps, Compressors, Fans, Turbines, and Motors. For pumps and compressors, expertise includes both centrifugal and positive displacement (e.g. reciprocating or screw) configurations.  Turbine knowledge and experience include hydraulic turbine generators (“hydroturbines”) as well as aircraft gas turbine engines and land-based gas or steam turbine power generation systems. Applications include green energy, power, process, petrochemical, paper, and water resource industries.

MSI uses advanced finite element analysis (FEA), rotordynamics, and torsional analysis tools, and uses computational fluid dynamics (CFD) to analyze 3-D steady or unsteady fluid flows and heat transfer, enabled by its 230 high speed processor supercomputer. MSI also uses top-of-the-line testing equipment, including multichannel FFT analyzers (up to 200 simultaneous channels) to accurately read the outputs of various vibration, stress/strain, and pressure sensors, as a function of both time and frequency. As a unique additional test capability, MSI uses motion magnification video cameras to amplify and display scene vibration by 1000x. MSI uses calibrated exciters while equipment remains running, to locate structural, rotor, and acoustic natural frequency resonances as they exist at any particular operating point, without interfering with machinery operation.  In addition, MSI performs stress, acoustic, dynamic pressure pulsation, electric current spectrum, and aero/hydraulic performance testing. 

MSI also has been project team leader in the development of advanced rocket turbopumps, as well as turbopump diagnostics, for the U.S. Air Force and NASA Marshall Space Flight Center. MSI is funded for several large projects with the U.S. Navy and Air Force involving vision-based systems that automatically evaluate and display/amplify machinery or system dynamic events.  As a result of these projects, MSI has developed its VibVue® vibration motion magnification system, which can magnify vibration 1000x in the full field-of-view of the equipment.  This system is available as a service, or for purchase.

Mechanical Solutions has a staff of approximately 30 technical professionals, many of whom are well known internationally in the area of pumps, compressors, and turbines.  For example, MSI’s Dr. Edward Bennett won the ASME Gopalakrishnan award for best pump fluids technologist, and was later awarded another ASME medal for CFD.    MSI’s Paul Boyadjis has won the Hydraulic Institute 2021 Standards Partner of the Year award. Since its founding in 1996, MSI has strived to provide best-in-class service throughout the world.
