Mechanical Shock Testing & Data Analysis


Mechanical Shock may be defined as a sudden change in velocity and is a major design consideration for a wide variety of systems. The structural response to mechanical shock must be measured and characterized during the engineering development of these systems so that they will survive all environments during their service lifetime. These environments may include (but are not limited to): handling and transportation shocks, shocks during system delivery to a target, and shock originating from an explosive or pyrotechnic event. These different shock environments have a velocity change range from about 1 meter per second to 51 meters per second (40 - 2000 ips).  Conversely acceleration magnitudes range from <1 g in earthquakes to 200,000 g in differentiated LDV measured pyroshocks.

This course will provide a comprehensive treatment of mechanical shock test techniques and data analysis for shocks from 100g to 200,000g. Mechanical shock instrumentation from low frequency techniques for underwater explosions (digitally filtered at 250 Hz as required by the US Navy) to high frequency techniques for ballistic shock will be reviewed in detail along with the techniques and data analyses to evaluate the instrumentation measuring these shocks.  This course is highly recommended for all lead technicians and managers of environmental test laboratories.  Managers and engineers on projects requiring shock testing will benefit greatly.

Mechanical shock test techniques from package testing to conventional mechanical shock machines to pyroshock simulations and Hopkinson bar techniques will be presented.  Design procedures for mechanical shock equipment will be discussed in detail.  Where possible, theoretical bases for mechanical shock test techniques are provided.  Mechanical shock data analysis and interpretation will be a major focus of all presentations and discussions and will include shock data examination and editing as well as interpolation, trend removal, and integration with MATLAB.  This course includes the state-of-the-art shock data evaluation techniques to detect “BAD” data, techniques to salvage “BAD” data and requirement for data acquisition systems to collect “GOOD” data.

 


Instructors

Dr. Vesta I. Bateman
Dr. Bateman is a mechanical shock specialist and retired from Sandia National Laboratories, Albuquerque , New Mexico after twenty-seven years of service.  She was the Facility Leader for the Mechanical Shock Laboratory at Sandia National Laboratories where she was responsible for a wide spectrum of mechanical shock testing including drop table, Hopkinson bar, horizontal pneumatic actuator, rocket rail, live pyroshock, and pyroshock simulation shock tests.  She has developed a unique shock isolator for a high shock, high frequency accelerometer as well as the test techniques and data analyses required to evaluate accelerometers and isolated accelerometers.  These technologies have been transferred to industry through Cooperative Research and Development Agreements (CRADA’s).  Dr. Bateman also developed high frequency Hopkinson bar testing with bars made of beryllium and a technique for reconstruction of dynamic forces from accelerometer measurements to assess material crush characteristics.  A paper by Dr. Bateman and her co-authors won the 1992 Henry Pusey Best Paper Award at the Shock and Vibration Symposium. She was awarded the IEST Edward O. Szymkowiak Award in 2003 for her leadership in Pyroshock Testing. She is the author of two chapters in Harris’ Shock and Vibration Handbook, the ISO Secondary Shock Calibration Standard, and the IEST Pyroshock Testing Recommended Practice as well as over 100 journal and conference papers and reports.  Dr. Bateman has a Ph.D from University of Arizona and taught for four years at Virginia Tech at the beginning of her career.
