Abstract: Embodiments of the present invention generally relate to a novel system, device, and methods for providing an isolator for components and instrumentation to isolate vibrations, shock, static or quasi-static loads, thermal loads, and electrical currents. The novel isolator has an asymmetrical shape, experiences uniform motion under quasi-static loading, and reduces the effective modal mass across a range of frequencies. The novel isolator outperforms conventional vibration isolators in terms of cost, schedule (manufacturing time and lead time), heat dissipation, and performance.

Abstract: Systems and methods for realizing practical applications of high speed digital image correlation (DIC) for dynamic quantities of interest are provided. In particular, a series of images are captured for a component of interest in which a non-filtered sensor and an analog low-pass filtered sensor are included within the region of interest for the series of images. Displacement signals are obtained for the component of interest, the non-filtered sensor, and the analog low-pass filtered sensor by applying digital image correlation processing to the series of images, which may also be wavelet filtered. Dynamic quantities of interest may be generated and derived from the displacement signals after having been wavelet filtered. Such dynamic quantities of interest based on the wavelet filtered DIC-derived displacement signal may be compared to sensor-derived dynamic quantities of interest to determine if aliasing is or is likely to be present.
