Applications The effects of shock are important in many engineering applications ranging from appliances to computers to ships to automobiles, trucks and military vehicles to high-performance aircraft and missiles. Shock is often part of the service and/or transportation environment. Military Standards such as MIL-STD-810 call for shock testing.
The possible effect of shock must be considered for almost every product that has to be shipped and handled. Care can be taken in a controlled environment but during the transportation phase the product within its package must be designed and tested to withstand the anticipated environment.
For Whom Intended Most engineers need specialized education in order to properly measure, quantize and analyze this generally unfamiliar environment, and to reproduce it in environmental test laboratories. This course is for packaging designers, test laboratory managers, engineers and aides. It also helps quality and reliability specialists and acquisition personnel in government and military activities, and their contractors.
Instrumentation specialists who will measure transportation, service and laboratory shock need this course. Metrologists learn about shock calibration of accelerometers and systems. Project personnel, structure and packaging engineers learn about developmental shock testing. Product assurance and acquisition specialists learn to evaluate shock test facilities and methods, and to interpret shock test specifications.
This course is designed to serve the varied needs of scientists, engineers, aides and senior technicians. The instructor maintains good balance between practical training and theory.
Brief Course Description The course commences with a review of basic dynamic theory and then covers natural frequencies and modes before discussion system response to shock. The Shock Response Spectrum (SRS) is discussed as it relates to shock measurement and testing, as well as design. The relative merits of various types of shakers and shock test machines are briefly considered before covering various shock test methods, including pyrotechnic shock testing. The course then covers shock measurements, also calibration. Shock resistant design is discussed, including the selection and use of isolators.
The theory and practice of package and product fragility analysis are covered in some detail, including the use of the damage boundary plot and the selection and testing of cushioning materials. Some typical shock test procedures and specifications are described, both military and commercial. Classroom (bring calculators) and nightly review problems measure progress.
Diploma Programs This course is required for TTi’s Dynamic Test Specialist Diploma. It may be used as an elective for any of TTi’s Specialist Diploma programs.
