Helicopter - Shock & Vibration Qualification of Equipment
This webinar reviews the source of vibration loading on a helicopter and describes standard qualification tests that are used to ensure the safe life of equipment on the aircraft. It describes how the vibration environment can be measured in terms of a Fatigue Damage Spectrum (FDS) and Shock Response Spectrum (SRS). These spectra are calculated from measured flight load data as well as from the vibration test. By comparing the flight spectra with the test spectra, the paper shows how highly optimized vibration tests are derived.
Although the paper deals specifically with helicopters, these techniques are now common in all industries, including: ground vehicles, offshore, power generation and electronics.
