【摘要】 利用Matlab软件的Simulink模块对冲击波位置传感器实验电路进行设计和仿真,详细分析了连接线电感、电阻寄生电感、电缆线长度和电阻阵列阻值设定等因素对电阻阵列电压信号下降沿弛豫时间的影响.其中连接线电感过高和电阻阵列阻值过低是造成电压下降沿弛豫时间延长的主要因素,可通过使用更粗、更短的电探针导线及合理设计电阻阵列来优化实验结果.更多还原

【Abstract】 The Simulink module of Matlab software was used to design and simulate the shock wave position sensor experimental circuit,and the influence of factors such as connecting wire inductance,resistance parasitic inductance,cable length and resistance value setting of resistance array on the relaxation time of the falling edge of the resistance array voltage signal was analyzed in detail.The high inductance of the connecting wire and the low resistance of the resistor array were the main factors that caused the relaxation time of the voltage falling edge to be prolonged.The experimental results could be optimized by using a thicker and shorter electrical probe wire and a reasonable design scheme of the resistor array.更多还原
