摘要:
航空发动机转速信号中存在高次谐波，信号在传感器与线缆组成的回路中谐振而发生畸变。基于低频电磁场有限元软件Ansys Maxwell，对某型转速传感器匹配不同参数音轮进行数值模拟分析，获得转速传感器感应电动势曲线。然后对仿真数据进行分析，识别音轮参数对转速信号的影响，并梳理出音轮优化设计流程。结果表明：通过设计合适的音轮参数，可以明显减少转速信号中高次谐波分量，增强信号抗干扰能力。
Abstract:
There are high harmonics in the speed signal of aeroengine, and the signal is distorted by resonance in the circuit composed of sensor and cable.Based on the finite element software of low frequency electromagnetic field Ansys Maxwell,the induction electromotive force curve of a rotating speed sensor is obtained by numerical simulation and analysis of the matching sound wheels with different parameters.Then the simulation data are analyzed to identify the influence of the parameters of the sound wheel on the speed signal,and the optimal design flow of the sound wheel is sorted out.The results show that the high-order harmonic components in the rotational speed signal can be obviously reduced and the anti-jamming ability of the signal can be enhanced by designing appropriate parameters of the sound wheel.
