Abstract: A health status assessment method and system for a transport vehicle automatic or semi-automatic access device is disclosed. The health status assessment system has at least one leaf actuated by a kinematic chain including at least one motor having an associated angular position or rotation speed encoder and at least one switch. The health status assessment method includes steps for analyzing at least one actuating cycle of the kinematic chain between a first and a second position wherein, during one said cycle, information is acquired representative of the electrical energy consumed by the motor, or position or speed information provided by said encoder or binary information indicating positions of switches. The method further includes dividing said cycle into a plurality of functional segments based on said acquired information, calculating at least one descriptor value, and then establishing a health status diagnosis of the health status assessment system.

Abstract: The invention relates to a health status assessment method for a transport vehicle automatic or semi-automatic access device comprising at least one leaf suitable for being actuated by a kinematic chain including at least one motor supplied with electricity and having an associated angular position and/or rotation speed encoder and at least one switch.

Abstract: Disclosed is an experimental simulation method for obtaining information relative to the reliability of an automatic passenger access door for a railway vehicle, including: a) fixing a non-downgraded and nominally adjusted door prototype, including a frame, a casement and an actuator driving the casement, on a test bench; b) subjecting the prototype to a series of tests; c) measuring, throughout the tests, signals characteristic of the performance of the door; and d) reiterating a) to c) with a downgraded door prototype at several downgrade levels. Step b) includes altering at least one of the context elements from among the orientation of the prototype around a first axis corresponding to the gradient, the orientation of the prototype around a second axis corresponding to the incline, the deformation of the frame and/or the casement, the line voltage of the door system, the weather conditions, or the presence of a door closure obstacle.
