摘要
对运载火箭测量系统二次电源在上电时产生的瞬态传导干扰源进行测量,得到该瞬态干扰时域以及频域信息。在测量数据的基础上,结合运载火箭常用的线缆,分析该瞬态干扰对邻近设备和线缆的耦合,研究不同线长、不同间距以及端接负载等情况的耦合响应。基于试验和仿真结果,对运载火箭线缆线束的选型、布线提供建议,对工程研究具有指导意义。
Transient interference caused by the secondary power supply of telemetry system is measured, and the time domain information and frequency domain information of this interference are obtained. Based on the measured wave, the commonly used cables of the launch vehicle are selected and simulated the coupling between power cable and other wires or equipments. Then, the coupling response of the cable length, space between cables, and termination loads are studied. The simulation and measurement results can direct the type and layout of the cables on the launch vehicle.
