Shock and Vibration conditions are often the most destructive factors present in demanding operating environments. Developing hardware to survive all the shock and vibration conditions potentially encountered by military hardware presents serious challenges. The purpose of this course is to convey a practical approach to meeting those challenges. This three day course provides a comprehensive treatment of the sources of shock and vibration (S&V) damage, methods of measuring and gathering ”life cycle” S&V information, and how to develop and execute military hardware tests. Both basic and advanced test and techniques will be addressed. The key components of test planning, analysis and execution will be addressed. S&V analysis techniques, sensors, test machines, control methods, and troubleshooting techniques will be covered. The information presented will be reinforced by case examples and exercises. Throughout the course, information will be grounded by real world “exemplars” of competent test engineering practice, providing practical approaches to applying the course material.
