Fault Diagnosis for Vehicle on-Board Equipments of High-Speed Railway Based on GA-ANFIS Model

Vehicle on-board equipment is the most important train control equipment in high-speed railways. Due to the low efficiency and accuracy of manual detection, in this paper, we propose an intellectualized fault diagnosis method based on adaptive neuro-fuzzy inference system (ANFIS) network. Firstly, we collect the fault information sheets that are recorded by electrical personnel, using frequency weighting factor and principal component analysis (PCA) to realize the data extraction and dimension reduction; Then, in order to improve the fault diagnosis rate of the model, using genetic algorithm (GA) to optimize the parameters of the ANFIS network; Finally, using the fault data of a high-speed railway line in 2019 to test the model, the optimized ANFIS model can achieve 96% fault diagnosis rate for vehicle on-board equipments, which indicating the method is effective and accurate.

Bridge Abutment

On the basis of different landform and multifarious topography in rugged mountainous area in southwest China, typical tunnel portals for single track tunnels in a new high speed railway line have been presented in the paper. The portal comprises headwall, shed tunnel, bridge abutment and its support. Portal with headwall is suitable for tunnel to resist front earth pressure on high and abrupt slope. Shed tunnel is placed in front of headwall so as to prevent rockfall; its outward part is built into a flared one. Meanwhile, the installation of bridge and its abutment are also included in the portal according to landform in the paper.

Multi Criteria Analysis

Предлагается модель анализа текущего состояния существующей инфраструктуры железнодорожной магистрали с целью последующего принятия организационно-технических решений на этапе инициации проекта высокоскоростной железнодорожной магистрали. Описываются возможные современные способы реализации высокоскоростного сообщения и их отличия в проектных и организационных решениях. Представлены основные элементы инфраструктуры железнодорожной магистрали, отдельно выделены факторы, влияющие на увеличение скорости движения. Представлена методика анализа, этапы и последовательность его проведения, принцип определения объектов анализа, возможные способы сбора данных по объектам анализа, перечень отраслевых геоинформационных и автоматизированных систем сбора и обработки оперативной информации по текущему состоянию инфраструктуры и эксплуатационной работе, методика обработки, обобщения, систематизации полученных данных для последующего анализа. Разработан общий алгоритм комплексного анализа технических и эксплуатационных параметров магистрали в виде последовательной блок-схемы. Данная модель актуальна при проведении анализа состояния инфраструктуры для всех существующих железнодорожных магистральных линий на территории России при выборе оптимальных и эффективных проектных решений совместно с экономическим обоснованием в процессе разработки комплексных мероприятий по внедрению высокоскоростного сообщения.
