Jim received his BS and Master’s Degrees in Mechanical Engineering from N.C. State University in 1973 and 1974, respectively. Jim has 35 years mechanical engineering experience including 32 years in Vibration Diagnostics; 28 years in setting up and implementing Conditioning Monitoring Programs, and 12 years experience in stress and fatigue analysis of machine and structural components. Jim is the President of Technical Associates of Charlotte, P.C.

Jim has published several articles in journals such as Sound and Vibration and P/PM Technology magazines. He has given presenta­tions to several engineering societies including the Vibration Institute, American Society of Mechanical Engineers (ASME), Acousti­cal Society of America (ASA), Electric Power Research Institute (EPRI) and the Predictive Maintenance Technology National Conference (through P/PM Technology). Jim has performed vibration analysis on machines, frames and foundations using a wide variety of single and multichannel spectrum analyzers, programmable data collec­tors, tape recorders, etc.
Vibration Diagnostic Evaluations including multichannel Modal and ODS Analyses and other advanced vibration evaluation tools have been performed by Jim on a wide variety of machines and support structures including centrifugal air compres­sors, rotary screw compressors, machine tools, paper machines, boiler ID and FD fans, circulating fans, pumps, rolling mills, draw texturing machines, winders, extruders, steam turbines, vertical pumps, cooling towers, refrigeration chillers, vacuum pumps and various types of single stage and multistage gearboxes. Operating speeds on these machines have ranged from as low as 1.5 RPM up to as high as 150,000 RPM.
Jim has now authored 6 Seminar Texts entitled “Entry Level Vibration Analysis”, “Analysis I”, “Analysis II”, “Analysis III”, “Advanced Vibration Analysis” and “Applied Modal & ODS Analysis”. Each of these textbooks comply with requirements of the ISO 18436-2 document. All seminar texts emphasize use of vibration signature analysis, high frequency enveloping (HFE), stress wave analysis and related Condition Monitoring technologies. These seminars are offered by Technical Associates at various locations in the United States, Europe, Asia, Australia, South Africa, Canada, Mexico, South America and in Central America. These multilevel seminars are given throughout the year by Jim as well as other qualified Analytical Group personnel that now has 10 specialists within the group; with 7 serving as Instructors and Analysts.
Jim now has 21 years experience serving as an Instructor in Vibration Analysis. Jim is also noted for development of the renowned “Illustrated Vibration Diagnostics Chart” that has been acquired by Vibration and Condition Monitoring engineers and technicians in 64 countries to date.
