| Abstract: |
| This paper aims to solve the problem that the output characteristics of magnetoelectric sensor for penetration fuze in different penetration environments are difficult to predict, and to grasp the influence of different structural parameters on the sensor output. Based on the structure principle of a new magnetoelectric sensor, a joint simulation research method is proposed. The research process is divided into two parts, one is to use ADAMS software to simulate the mechanical characteristics of the magnetoelectrical sensor inertial system, and the other is to use COMSOL software to simulate the magnetoelectrical characteristics of the sensor electromechanical conversion components. The input of the simulation model is the overload information of the warhead in the penetrating process. The simulation results of the simulation model are verified by the measured data obtained from magnetosensors in multiple shock loading tests. Change the relevant parameters of the simulation model, simulate and analyze the influence of the sensor structure on the simulation output characteristics. The verification results showed that the average absolute error of the simulated penetration time is about 138 μs, and the average relative error of the simulated voltage value at the penetration time is about 5.9%. Under the premise of given mechanical environment, the relative height of the coil and the magnet in the magneto-electric sensor will affect the positive and negative amplitude of the output signal and the time of the peak. The number of coil turns and the interval between the coil and the magnet will only affect the amplitude of the signal. In conclusion, the simulation error is within the controllable range, which verifies the correctness of the joint simulation model and the feasibility of the research method. The simulation model can provide guidance for the design of the magnetoelectric sensor for the penetration fuze, and provide a new idea for further verifying the performance of the initiation control system of the penetration fuze. |
