摘要
装甲车诱导轮加强筋处在服役运行过程中容易产生表面裂纹,从而给车辆的安全服役带来重大隐患。利用CIVA仿真软件模拟了点式探头倾斜对涡流密度的影响;基于实际应用场景设计了涡流阵列检测探头,探究了激励频率和提离对涡流信号的影响;然后,与点式探头进行了试验与模拟的对比,并在带漆诱导轮上进行了验证。最终确定了矩形线圈的最佳参数,在实际检测的过程中,该涡流阵列探头较点式探头信号幅值平均提升了30%,检测效率提升了85%。
The reinforcement ribs of the induction wheels of armored vehicles are prone to surface cracks during service operation,which can pose significant risks to the safety of the vehicle during service.This paper used CIVA simulation software to simulate the effect of point probe tilt on eddy current density.Based on practical application scenarios,an eddy current array detection probe was designed to explore the effects of excitation frequency and lift off on eddy current signals.The experiment and simulation were compared with point probes,and verified on a painted induction wheel.The optimal parameters of the rectangular coil were ultimately determined,and in the actual detection process,the designed eddy current array probe increased the average signal amplitude by 30%and the detection efficiency by 85%compared to the point probe.
