Abstract

Appareil destiné à mesurer la force spécifique inertielle et la vitesse angulaire d'un corps en mouvement au moyen d'accéléromètres montés sur des axes perpendiculaires, chaque accéléromètre vibrant axialement. L'appareil comprend un mécanisme d'entrainement pour faire vibrer chaque accéléromètre en vue de produire des signaux de sortie et un processeur de signaux pour dériver des accéléromètres, la force spécifique et la vitesse angulaire pour les axes respectifs. On obtient un rendement amélioré en utilisant des accéléromètres vibrants jumelés et un circuit de préséparation.Apparatus for measuring the specific inertial force and the angular velocity of a moving body by means of accelerometers mounted on perpendicular axes, each accelerometer vibrating axially. The apparatus includes a drive mechanism for vibrating each accelerometer to produce output signals and a signal processor for deriving accelerometers, specific force and angular velocity for the respective axes. Improved efficiency is obtained using twin vibrating accelerometers and a pre-separation circuit.
