Vibration: Resonance Search & Dwell It is generally accepted that the steady-state vibration environment is of such low acceleration amplitude that failure does not occur due to non-resonant inertial loading. - Damage is most likely to occur when some element or component of a product has a natural frequency which is excited by the environment. - The identification of those frequencies becomes critical in designing a package system. The purpose of the bare product vibration testing is to identify the natural or resonant frequencies of the critical components within the product. - Response of a product or component to input vibration may be represented by a curve similar to that shown in Figure 14.5.Vibration: Resonance Search & Dwell It is generally accepted that the steady-state vibration environment is of such low acceleration amplitude that failure does not occur due to non-resonant inertial loading. - Damage is most likely to occur when some element or component of a product has a natural frequency which is excited by the environment. - The identification of those frequencies becomes critical in designing a package system.
