Abstract

The ball rotor flameproof device was widely used in the fuze safety system

and deep research on the test method of the motion law of ball rotor had positive meaning since some of the ball rotors can′t move to the idea position in engineering practice.A test method of the motion law of ball rotor based on the change of magnetic field intensity had been put forward in this paper and related mathematical model had been established.Also

the influencing factors had been analyzed and calculated and simulation experiment had been completed using the centrifuge modeling the ballistic environment.The signal detected by magnetic sensor increases significantly when magnetic materials were used in the experiment.The trajectory of ball rotor had also been simulated and the results are in good accordance with the graphs obtained in the experiment

so the feasibility of the test method is confirmed.
