摘要
Abstract
The branch wiring harness network of the aircraft ejection seat is a key component for information exchange and signal transmission inside the ejection seat.To improve the accuracy and reliability of its electri-cal measurement,the aircraft wiring harness network is modeled and simulated based on time domain reflectom-etry(TDR).Firstly,for the key module of the ejection seat,the wiring harness network,a general electrical e-quivalent model of the wiring harness is constructed,and its parameters are analyzed.Then,taking the internal branch wiring harness network of ejection seat as the research object,the fault propagation process is analyzed by the TDR.Finally,the corresponding simulation model is built in MATLAB for verification and analysis.The simulation results show that,in the ejection seat,high-frequency pulse signals not only experience transmission and reflection at the fault locations,but also at the branch junction points.关键词
