| 目的 解决侵彻引信用磁电传感器在不同侵彻环境下输出特性难以预知的问题，掌握不同结构参数对传感器输出的影响。方法 基于一种新型磁电传感器的结构原理，提出一种联合仿真研究方法，研究过程分为2部分，一部分是利用ADAMS软件进行磁电传感器惯性系统的力学特性仿真，另一部分是利用COMSOL软件进行传感器机电转换元件的磁电特性仿真，仿真模型的输入是战斗部在穿靶过程中的过载信息。通过磁电传感器在多次冲击加载试验中获取的实测数据，对仿真模型的仿真结果进行验证。改变仿真模型的相关参数，模拟并分析传感器结构对仿真输出特性的影响。结果 仿真穿靶时间的平均绝对误差约为138 μs，穿靶时刻仿真电压值的平均相对误差约为5.9%。在给定力学环境的前提下，侵彻引信用磁电传感器中的线圈与磁铁的相对高度会影响输出信号的正负、幅值以及波峰出现的时间，线圈匝数、线圈与磁铁之间的间隔仅对信号的幅值产生影响。结论 仿真误差在可控范围内，验证了联合仿真模型的正确性与该研究方法的可行性。该仿真模型可以为侵彻引信用磁电传感器的设计提供指导，并为后续进一步验证侵彻引信起爆控制系统的性能工作提供了新的思路。 |

| 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. |
