Modeling and Simulation of Fuze Flight Rotating Speed

The ammunition fuze is the control device to control the projectile initiation in the proper position and the best time of during the flight. In view of the poor life-likeness of the current fuze rotation speed model which directly affects the centrifugal test of the fuze, so it cannot judge the quality of the fuze scientifically. In this paper the working mechanism of fuze centrifugal environment is comprehensively Analysed, the mathematical model of rotational velocity attenuation law of two kinds of projectiles constructed, and the actual measurement of projectile rotation velocity is completed based on radio technology, the motion parameters of the model calculated ,and the validity of the model is verified by simulation .
