Experimental simulation process, for obtaining information relative to the reliability of an automatic passenger access door

The invention comprises an experimental simulation method for obtaining information relative to the reliability of an automatic passenger access door for a railway vehicle, this method comprising steps consisting of a) fixing a non-downgraded and nominally adjusted door prototype (4) on a test bench (2), the prototype comprising a frame (40), a casement (42) and an actuator driving the casement, b) subjecting the prototype (4) to a series of tests, c) measuring, throughout the entire series of tests, signals characteristic of the performance of the door, d) reiterating steps a) to c) with a downgraded door prototype at several downgrade levels. Step b) consists of altering at least one of the context elements from among the orientation of the prototype around a first axis (Y1) corresponding to the gradient, the orientation of the prototype around a second axis (X1) corresponding to the incline, the deformation of the frame (40) and/or the casement (42), the line voltage of the door system, the weather conditions. A further context element may be the presence of an obstacle to the closure of the door.
