    • Electrical currents are detected and analyzed across structural members in a structural joint, such as a fastener of a vehicle. In some aspects, printed circuit boards etched with Rogowski coil circuits are inserted proximate the structural members in the structural joint. The Rogowski coil circuits may detect an electrical current as it flows through the structural joint. An integrator may integrate a transient current to generate an output signal, such as when the vehicle is subjected to an electrical charge. The output signal may be transmitted to an Integrated Vehicle Health Management (IVHM) system for analysis. In various aspects, the IVHM system may enable recording and reporting of various aspects of the current to enable maintenance, inspection, or real time/near real time health assessment of the vehicle.
    • 在诸如车辆的紧固件的结构接头中的结构构件上检测和分析电流。 在一些方面,用罗戈夫斯基线圈电路刻蚀的印刷电路板被插入结构接头中的结构构件附近。 Rogowski线圈电路可以在流过结构接头时检测电流。 积分器可以集成瞬态电流以产生输出信号,例如当车辆经受电荷时。 输出信号可以传输到综合车辆健康管理(IVHM)系统进行分析。 在各个方面,IVHM系统可以使得能够记录和报告当前的各个方面,以实现对车辆的维护,检查或实时/接近实时的健康评估。
