Abstract
Abstract To assess the contradiction between ballistic safety and ignition reliability in traditional rocket projectile inertial initiation mechanisms, this study focuses on the recognition of graze bursting ignition signals for a specific type of rocket projectile. By utilizing a finite element numerical simulation method to model the small-angle impact of the rocket projectile on a target, the overload information can be extracted from the ignition mechanism. The accuracy of the simulation model can be validated by comparing it with data obtained from live ammunition tests. Through a series of simulations, the ignition threshold can be determined by the maximum velocity change vector within different time windows of the ignition mechanism. And the integration algorithm is used to accumulate the overload value of the ignition mechanism in the time window to judge whether the velocity change threshold is reached, and then judge whether to output the ignition signal. The algorithm verification shows that the algorithm can effectively identify the ignition signal under the set ignition threshold. This method provides a basis for recognizing the graze bursting ignition signal.
