摘　　要：在已实证高速列车部件维修关系网络为复杂关系网络的基础上,根据复杂网路可靠性理论,将复杂网络的抗毁性测度指标中的节点介数和节点凝聚度作为分析高速列车系统部件重要性及其在系统局部网络中连通性的指标,据此筛选出系统中的重要部件和冗余不足的部件,为深入研究高速列车部件可靠性提供新思路。以CRH3型高速动车组牵引系统为例的实证表明,基于复杂网络可靠性的计算方法能够正确筛选出系统中的重要部件和冗余不足的部件,从而为后续的系统可靠性设计和冗余设计提供科学依据。The maintenance relationship network for the components of high speed railway has been demonstrated a complex relationship network.Based on this and according to the reliability theory of complex network,the node betweenness and node agglomeration in the invulnerability index of complex network were regarded as the indices to evaluate the importance of the components for high speed train system and analyze the connectivity in the local networks of the system.In this way,the important components and redundancy deficient ones were selected,which provided new ideas for the further reliability study of the components for high speed train.Taking the traction system of CRH3 high speed train as a case study,the results show that the calculation method based on the reliability of complex network can correctly select the important and redundancy deficient components in the system,which provides scientific basis for the follow-up system reliability design and redundancy design accordingly.
