Velocity equation for grenades while impacting on dry sand media

Popis výsledku v původním jazyce

This paper deals with the collision of sphere shape grenades with sand media. The central issue of the article is the establishing of an empirical velocity equation of the grenade while impacting on sand that is used to solve motion equations of the mechanical mechanism inside the impact grenade fuze. The paper focuses on impact velocities that are lower than 5 m s−1. An experiment was conducted to study the velocity of the grenade while impacting on dry sand. A high-speed camera video was used to capture the grenade positions. The grenade velocity in the impact process was generated from these video data. Some types of fitting curves are used to regress the velocity equation of the grenade while interacting with the sand media and the best-fitting model is chosen. The result shows the regression curve has a high correlation with the experiment data for grenade velocities below 5 m s−1. The received regression equation is useful for analyzing the working ability of the inertial mechanism inside the impact grenade or analyzing and choosing the appropriate parameters of each part in the inertial mechanism to meet the required characteristics of the mechanism.
