fichier parcours

français vers anglais Technique / Génie Transport / expédition
This is from the technical specifications for a rail bogie, specifically the section involving effects of engine torque on the axles. The section heading is "Couple équivalent en parcours simulés au niveau du moteurLa vérification des organes ponts, roulements et dentures s’effectuent en partant du couple" (which I translate as "Equivalent torque in simulated paths on the the engine level"). I'm not experienced in this field, so I don't know exactly what is meant by "parcours", but in particular, how should "fichier parcours" be translated here? I can't find any other meaning for "fichier" than "(data) file" or "index" (as in a library), but I don't see how that makes any sense here.

Le surcouple dynamique est considéré à 3 fois le couple au moteur de 1586 m.N, donc4758 m.N avec une occurrence de 150 000 fois dans la vie du matériel (40 ans). Cependant, compte tenu de la présence d’un surcouple permanent (report de couple d’unessieu sur l’autre), c’est à dire que la proportion du couple moteur transmis par un pontpeut varier, il est appliqué pour la vérification des roulements et dentures une majoration. En conséquence les ponts verront un couple moyen supérieur à la moitié du couple moyenmoteur (Cm), calculé à partir du fichier parcours de ligne joint.

The dynamic overtorque is considered at 3 times the engine torque of 1586 mN, thus 4758 mN with an occurrence of 150,000 times in the equipment life (40 years). However, due to the presence of a permanent overtorque (transfer of torque from one axle to the other), meaning that the proportion of the engine torque transmitted by an axle may vary, an increase is applied for the verification of the unibal bearings and gearings. Consequently, the axles will see an average torque greater than half the average engine torque (Cm), calculated on the basis of the file paths(?) of the attached line.

fichier de parcours de ligne joint it is the "fichier de parcours de ligne" that is attached, for starters. I won't correct your translation which is a bit "iffy" but I will say that JL01 is on the right track. They are referring to line data for the particular route or corridor. "Parcours" can also mean "trip". This "fichier" is a standard document, a reference data sheet, which gives details of things like uphill and downhill gradient, curves and their radius etc. It is from this that the engineers can calculate the possible incidences of excess torque etc.

There is a simulation, involved therefore the "fichier parcours" is, most likely, the route data for said simulation.

route data file

This is what is used in railway simulation:

"You may select from any route data file and from any train data file on disk."

"Generate route notes (stored in the rnote field of the Route data file), and further edit these as required."
