摘    要:传统的运载火箭电磁阀极性测试往往通过“耳听手摸”的方式,存在漏检误检、测试记录不可量化及数据追溯、无法精准判读、测试效率低等问题。因此对运载火箭典型姿控电磁阀开展了漏磁性能的测量与量化分析,掌握阀体各部位漏磁场分布规律、漏磁场随距离衰减变化规律、电磁阀之间漏磁场相互影响情况,并提出了一种非接触式的可视化电磁阀极性检测系统设计方法,采用三冗余敏感探头采编设计保证极性检测准确性,经试验测试验证,实现了无需精确安装即可100%检测电磁阀动作及时序动作精准判读,提升了电磁阀极性检测能力和测试效率。该系统已成功应用于大型运载火箭的总装测试流程中,对于提升运载火箭自动化测试水平具有重要意义。

关 键 词:运载火箭  电磁阀  漏磁性能  极性检测

Quantitative Study on MFL Characteristics of Launch Vehicle Solenoid Valves and Design of Polarity Detection Device
Abstract:Traditional testing method for solenoid valve polarity of launch vehicles is often detected through "listening and touching", which has problems such as missed detection and false detection, inability to accurately interpret, and low testing efficiency. Therefore, the measurement and quantitative analysis of the magnetic leakage performance of typical attitude control solenoid valves were carried out to grasp the distribution of magnetic leakage fields in various parts of the valve body. A non-contact visual polarity detection system design method for electromagnetic valves was proposed, and the accuracy of polarity detection was ensured by using three redundant sensitive probes for sampling and programming design. Experimental testing was verified, it has achieved 100% detection of electromagnetic valve actions and accurate interpretation of timely sequence actions. This system was successfully applied on the testing process of large launch vehicles and has improved the automation testing level of launch vehicles.
Keywords:launch  vehicle  solenoid  valves  MFL  characteristics  polarity  detection
