Best Presentation Award SABO Symposium 2023, CSIR ICC 9 -11 May 2023
Congrats on Best Oral Presentation Gold Award going to Lafras Fritz et al for "Evaluation of Weapon Dynamics and Weapon Mount Dynamic Response",
"The evaluation and measurement of the dynamic response of weapon systems is a continual challenge. The measurements of interest are usually estimated using accelerometers, or laser-based displacement
sensors. The sensors used must have adequate full-scale range to ensure limits are not exceeded, as well as sufficient dynamic range to ensure the internal resonance frequency is not activated. The typical shock-
loadings experienced during weapon firings are of a small-time scale. Very often, the entities-of-interest are not accelerations, but rather displacements and velocities. The computing of these quantities by numerical integration also poses some risks. The frequency response of the signal, the integration strategy, and the initial conditions are often responsible for the incorrect integration results. Added inconveniences are that accelerometers can sometimes not be placed at the location of interest (due to thermal constraints or inaccessibility of cabling), and that multiple uniaxial accelerometers, or another triaxial accelerometer) would be required for every location of interest. Flamengro has developed an algorithm to utilise Computer Vision (CV) to obtain full-field displacements of a tracked object, or “marker”. The algorithm determines the position of a marker in the image, and the displacements are calculated from the positions. The velocities and accelerations are determined by numerical differentiation instead. "
