The ESTECH 2017 conference runs from May 9-11 in Louisville, Kentucky. During this time, two Thermotron engineers will present at conference sessions, starting with Dr. Benjamin Shank, mechanical engineer, on Tuesday, May 9, at 8 a.m. 

Ben’s talk, titled Exploring the Limits of Mid-Field Pyroshock on Electrodynamic Shakers can be summarized as such: conventional wisdom, as codified by MIL-STD-810G, holds that electrodynamic (ED) shakers are not useful for reproducing vibration environments in which frequencies above 3 kHz are important. This is perhaps most noticeable in Method 517: Pyroshock, where the procedure for mid-field (3-10 kHz) testing with a mechanical device explicitly excludes ED shakers. This talk summarizes recent efforts to generate pyroshock-like transients on a range of small- to medium-sized ED shakers with meaningful SRS content up to 10 kHz.

Benjamin Shank earned a Ph.D. in physics from Stanford University for characterization and modeling of quantum calorimeters for the Cryogenic Dark Matter Search. His work at Thermotron focuses on vibration test system control and associated applications.

Following Ben is Milt Bos, supervising mechanical engineer-vibration test systems. Milt is presenting on Wednesday, May 10 from 3:15-5:15 p.m. The goal of his session, titled Fixture Validation – How to Determine the Quality of a Fixture, is to equip those attending with concepts that will prove valuable in the process of determining fixture quality. Two fixtures will be evaluated and methods of finding control points and of determining acceptable functionality and methods of use will be examined. The presentation draws on the knowledge-base of a manufacturer of ED shakers and associated fixtures. Basic ideas of vibration control and response evaluation will be presented, with a focus on the limits that can be successfully reached with real fixtures.

Milton (Milt) Bos received his bachelor of engineering degree from Calvin College in 1986. He has been employed at Thermotron for eighteen years. He has focused exclusively on electrodynamic shakers and their accessories. He has been involved in every aspect of design of the shakers and sliptables and continues to do research and development on new features and new models.

Those attending the conference are encouraged to visit the Thermotron booth (booth 301) to talk with the presenters, see a live demo of Thermotron’s vibration controller, receive free giveaways, and learn more. We look forward to talking with you there.
