Abstract

Abstract: In view of the failure situation of the vibration sensor carried by the projectile without anti-overload treatment, two failure cases of the vibration sensor on the projectile are analyzed, and the internal structure of the vibration sensor on the projectile is simplified as the mechanical model of the fixed beam. The results show that the interior structure of the projectile-borne vibration sensor has a direct impact on its impact resistance, and the impact resistance of the projectile-borne vibration sensor placed parallel to the direction of acceleration propagation is higher than that of the projectile-borne vibration sensor perpendicular to the direction of acceleration propagation. The results can provide reference for selection and placement of vibration sensors.
