摘要: 在DIMA平台开放性体系架构的背景下,飞机航电与机电等系统功能逐渐渗透融合,面向DIMA架构的全电刹车系统是未来飞机刹车系统的主流设计趋势,但目前尚未形成针对DIMA架构下全电刹车系统的故障传播行为分析与评估方法。针对上述问题,首先结合DIMA架构特征和全电刹车相关标准,分析面向DIMA架构下的全电刹车系统分层架构,在此基础上构建全电刹车系统任务-功能-资源层次模型。其次,考虑到DIMA平台资源共享的特点,结合系统层次模型开展系统耦合关联分析,引入Floyd算法计算间接耦合矩阵以及路由矩阵,通过构造失效严重程度矩阵量化系统关联耦合度,建立系统故障传播结构模型,综合考虑故障路径传播概率和系统边缘介数,构建DIMA架构下全电刹车系统故障传播强度模型,以识别系统故障传播关键路径,完成故障传播行为分析与评估。最后通过实例分析,以验证所提方法的正确性与合理性。

Abstract: Against the background of the open architecture of Distributed Integrated Modular Avionics platform, aircraft avionics and electromechanical system functions gradually permeate and integrate with each other. The DIMA architecture oriented all-electric brake system is the mainstream design trend of the future aircraft brake system; however, the failure propagation behavior analysis and evaluation method for the all-electric brake system under the DIMA architecture has not been formed yet. Aiming at this problem, we analyze the layered architecture of the DIMA architecture oriented all-electric brake system, combining the characteristics of the DIMA architecture and relevant standards of all-electric brakes, and on this basis, establish the task-function-resource hierarchical model of the all-electric brake system. Secondly, considering the resource sharing characteristic of the DIMA platform, we conduct the system coupling relation analysis, calculate the indirect coupling matrix and routing matrix by introducing the Floyd algorithm, establish the system structure of the fault propagation model by constructing the failure severity associated coupling matrix quantization system, and build the fault transmission intensity model of the all-electric brake system under the DIMA framework considering fault path transmission probability and the edge betweenness to identify the critical path of system fault propagation and complete the analysis and evaluation of the failure propagation behavior. Finally, an example is provided to verify the correctness and rationality of the proposed method.
