Abstract:
A dynamic model is constructed for a vehicle mounted automatic mortar, including the motion of automat. The muzzle disturbance and its effects on firing density are analyzed by the way of the dynamic simulation of muzzle motion on the uninterrupted fire. The obtained results show that the muzzle motion has small impacts on firing density because the motion is periodic, and the t ime at which project flies out of muzzle is far from that of mot ion peak value although the muzzle translates within the area of 30 mm× 50 mm, and rotates from - 0. 4b to 1. 5° when the mortar continually launches with 4 rounds. Finally, the trend of muzzle motion under various elevat ing and traverse angles and the related sensitivity analysis are represented by the tool of net graph, and some suggestions for refined design are presented, which is of importance in development of this weapon system.
