摘要: 为研究强电磁脉冲对单兵外骨骼助力系统上硅微惯性传感器的电磁损伤效应,通过理论计算和试验分析相结合的方法,对硅微惯性传感器的电磁损伤阈值、电磁易损器件和损伤模式开展研究。采用Agrawal传输线理论模型和格林函数法,计算硅微惯性传感器在电磁脉冲环境中由直连线缆耦合并传导至信号传输端口的强电脉冲,并开展信号传输端口的强电脉冲注入试验和传感器损伤模式分析。研究结果表明:硅微惯性传感器的强电脉冲损伤阈值为780 V,电磁易损元器件为前端电容和信号放大器,其主要损伤模式为电容的高电压击穿和放大器的大电流烧毁。

Abstract: In order to study the damage effect of strong electromagnetic pulse on the micro-silicon inertial sensor of exoskeleton robotic system, the electromagnetic damage threshold, vulnerable devices and damage modes of micro-silicon inertial sensor are studied through theoretical calculation and experimental analysis. The strong electric pulse coupled and transmitted to the signal transmission ports by cables which are directly connected to sensor in electromagnetic pulse environment is calculated by using Agrawal transmission line theory and Green's function. And the strong electric pulse injection experiment of signal transmission ports and the damage mode analysis of sensor are carried out. The result shows that the damage threshold of micro-silicon inertial sensor is 780 V, the electromagnetic vulnerable components are front-end capacitor and signal amplifiers, and the main damage modes are high voltage breakdown of capacitor and high current burnout of amplifiers.
