摘要
捕获跟踪系统(ATS)作为数据中继卫星(TDRS)的核心载荷,其高可靠运行与故障快速分析能力至关重要。针对这一需求,文章应用基于模型的系统工程(MBSE)设计方法,通过SysML语言构建包含逻辑结构、端口约束与行为活动的设计模型,并应用新构造型定义组件功能和端口的故障模式及逻辑关系,形成功能-可靠性集成模型。以该模型为基础开展可靠性分析,实现了对捕获跟踪系统机构转动参数异常问题的故障树(FTA)自动分析。研究结果表明,文章构建的可靠性集成模型准确表征了捕获跟踪系统的故障状态及故障传递关系,可有效支撑系统功能与可靠性的协同设计,在数据中继卫星系统设计中的有工程应用价值。
As the core payload of Tracking and Data Relay Satellites(TDRS),the Acquisition and Tracking System(ATS)requires high reliable operation and rapid fault analysis capabilities.To address these demands,this study employs a Model-Based Systems Engineering(MBSE)approach to develop a design model encompassing logical architecture,port constraints,and behavioral activities using SysML.Novel stereotypes are defined to characterize component functions and to describe logical relationships of port failure modes.On this basis,an integrated function-reliability model is established.This model enables automated fault tree analysis(FTA)to support anomaly diagnosis in ATS.The results demonstrate that the proposed model accurately characterizes the fault states and fault propagation mechanisms of the ATS.The approach exhibits strong applicability in supporting the collaborative design of system functions and reliability,demonstrating practical engineering value in the design of TDRS.
