摘要
主要针对适用于低温低气压复杂环境下高空飞行器推进电机的可靠性研究,特别是控制器环境适应性、通讯可靠性等共性问题。分析了影响高空飞行器推进电机可靠性的主要因素,从方案的选择,软、硬件设计及总体上考虑,软防硬治,通过滤波、隔离、屏蔽、去耦、接地等硬件措施防患于未然,再借助于软件的方法来监测和排除故障。在可靠性设计中采取了三点关键技术,异构通讯冗余设计、热降额设计和人机工程技术,预防和改进整装结构中的隐患及薄弱环节,降低了系统故障率,研究结果具有较强的工程实践意义和应用价值。
The reliability of spacecraft propulsion motor under the condition of low temperature low pressure was research,especially the controller environment adaptability,communication reliability and other common problems.The main factors influencing the reliability of the high altitude flight vehicle propulsion motor were analyzed,about the choice of scheme,software and hardware design and the overall consideration,hardware measures nip in the bud,such as filtering,isolation,grounding,shielding,decoupling,and then the software method was adopted to monitor and troubleshoot.Reliability design adopted three key technologies,redundancy design,thermal control technology and the man-machine engineering,to prevent hidden dangers of the bulk structure and improve the weak links.This design can reduce the system failure rate,and the result of the study has strong practical significance and application value.
