Categories > Technical / Mechanical Category:      Mechanical Shock Techniques      Program Duration : 5 Days Program Date : 21-25 April, 2012 Program Location : Cairo, Egypt Program Fees : US$3200/Per Person    PROGRAM INTRODUCTION: 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. PROGRAM OBJECTIVES: 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. WHO SHOULD ATTEND? Most engineers need specialized education in order to properly; measure quantize Analyze this generally unfamiliar environment and to reproduce it in environmental test laboratories. 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.
