    摘要： Disclosed are an activation control method and apparatus for a railway train. The method includes that: at least one activation request sent by at least one master controller of a railway train is received; a number of at least one master controller sending the at least one activation request is determined; when there are a plurality of master controllers sending the at least one activation request, the railway train is controlled to perform an emergency braking; and when there is one master controller sending the at least one activation request, it is determined that a target master controller has a permission to control the railway train, wherein the target master controller is a unique master controller sending the at least one activation request. The present invention solves the problem in the related art of potential safety hazard of a double-vehicle activation processing method.

    摘要： A method, device and system for controlling air supply of fuel cell, and a railway vehicle are disclosed. The method includes: continuously inputting reaction air to a fuel cell based on a preset excess coefficient, wherein the preset excess coefficient is greater than a standard excess coefficient; in a case that a working power of a target object is increased, detecting whether a current excess coefficient is less than or equal to the standard excess coefficient in real time or regularly; and if it is detected that the excess coefficient is less than or equal to the standard excess coefficient, increasing the current excess coefficient to the preset excess coefficient. The disclosure solves the technical problem that the existing fuel cell is relatively slow in response when the electricity consumption demand is increased.

    摘要： Some embodiments of the present disclosure provide an energy-absorbing anti-creeper and a train vehicle with the energy-absorbing anti-creeper. The energy-absorbing anti-creeper includes: a guiding cylinder (10), an energy-absorbing material (20), a collision mechanism (30) and a discharging mechanism (40) for discharging the energy-absorbing material (20) being arranged at the first end of the guiding cylinder (10). A first end of the guiding cylinder (10) is configured to be in assembly connection with a train. The energy-absorbing material (20) is filled in the guiding cylinder (10). The collision mechanism (30) is arranged at a second end of the guiding cylinder (10). The first end of the guiding cylinder (10) and the second end of the guiding cylinder (10) are two opposite ends of the guiding cylinder (10). The energy-absorbing material (20) is extruded to deform when a collision occurs between the collision mechanism (30) and a collision object.

    摘要： A suspension frame assembly of a magnetic levitation vehicle, comprising a plurality of suspension frames (100) which are connected successively. The suspension frame (100) comprises: two longitudinal beams (1) arranged in parallel, supporting wheels (3) and holding arms (11) being fixedly arranged on two ends of each longitudinal beam (1); and two anti-side rolling devices (4) mounted between mounting racks of the two supporting wheels (3) arranged on the same ends of the two longitudinal beams (1); two longitudinal beams of one suspension frame (100) are hingedly connected to two longitudinal beams of an adjacent suspension frame, respectively; air spring holding arm beams (8) for mounting air springs are arranged on a hinged part between the two suspension frames (100); the air spring holding arm beams (8) are mounted on the holding arm (11) of one of the two hingedly connected longitudinal beams (1); and the holding arms (11) of the two longitudinal beams at two ends of the suspension frame assembly are mounted with the air spring holding arm beams (8) for mounting the air springs. The suspension frame assembly is light in weight, and can effectively improve the suspension ability.
