摘要： Disclosed are a stress-resistant, creep-resistant, high-temperature resistant and high-insulation sheath material for a maglev train cable, and a manufacturing method and use thereof. A multiple chemical crosslinking structure is constructed by blending a functional polyvinylsilicone grease with ultra-high molecular weight polyethylene (UHMWPE) and a ceramicized silicone rubber as a cable material matrix and using electron beam irradiation. In addition, organic/inorganic fillers in the matrix can form physical crosslinking points in the material. A physical-chemical dual crosslinking structure is constructed in the matrix, which can limit the motion and relaxation of molecular chains and improve the interaction between the insulation layer and sheath layer and refractory layers such as fillers and mica tapes to avoid the relative displacement during the laying and operation and improve the high-temperature resistance, creep resistance and stress relaxation resistance of a UHMWPE cable sheath material.

摘要： A method for trains to establish a virtual coupling (VC) operation mode, which includes: successively determining whether adjacent preceding and following trains on a same line meet initial conditions and formation conditions of the VC; and performing VC on both trains meeting the initial conditions and formation conditions, and determining the VC of all trains on the line through the above determination method to obtain an overall VC. The method further including controlling operation of a leading train in the overall VC according to driving permission of the VC, and controlling operation of each of remaining following trains based on communication with the corresponding adjacent preceding train in combination with the following train's own driving information. An establishment process of forming a VC operation mode, thereby improving efficiency of train transportation and flexibility of organization and scheduling.

摘要： An insulating element for a high-power plug connector system comprises at least one stop formation for limiting the distance of insertion into the high-power plug connector system and at least one cutout, which allows contact to be established between a receivable high-power contact and at least one electrically conductive bar. The insulating element has at least one retaining formation, which is located on the periphery of the insulating element, near the stop formation.

摘要： A monitoring method and system monitor a transmitted current that is injected into conductive components of a route traveled by vehicle systems, monitor a received current that represents a portion of the transmitted current that is conducted through the conductive components of the route, examine changes in the transmitted and/or received current over time to determine when the vehicle systems are on the route between a first location where the transmitted current is injected into the conductive components and a second location where the received current is monitored, and examine the changes in the transmitted and/or received currents. The changes are examined to identify (a) a contaminated portion of a surface on which the route is disposed, (b) a foreign object other than the vehicle systems that is contacting the route, and/or (c) a damaged or broken portion of at least one of the conductive components of the route.

摘要： A locomotive control system includes one or more processors configured to determine quality of service (QoS) parameters of locomotive devices communicating data with each other in an Ethernet network that is configured as a time sensitive network (TSN) and that is onboard a locomotive. The one or more processors also are configured to determine available communication pathways in the TSN through which the locomotive devices are able to communicate the data. The one or more processors also are configured to select one or more of the available communication pathways and to designate communication times at which the data is communicated between the locomotive devices to satisfy the QoS parameters of the locomotive devices.

摘要： A locomotive control system includes a controller configured to control communication between or among plural locomotive devices that control movement of a locomotive via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the locomotive devices to communicate using time sensitive communications, a different, second set of the locomotive devices to communicate using best effort communications, and a different, third set of the locomotive devices to communicate using rate constrained communications.
