This article paper the influence of rails
inclination on the behaviour of a railway vehicle in circulation on a curve
and on alignment. A comparative study is performed the behaviour of a vehicle which
circulates on rails without inclination and another circulating on
inclined on rails. This study shows the interest on the inclined rails.
The effects of the transverse and longitudinal stiffness of the primary
suspension, the angle of inclination rail and the equivalent conicity of the
wheels are considered to evaluate the vehicle's behaviour in curve and
transverse stability. The simulation of the vehicle moving in curve
with inclined rails shows that the transverse displacement of this
vehicle decreases if the inclination of the rails increases. Moreover, the
stability of a wheelset which circulates on inclined rails is comparable to
the stability of a wheelset which circulates on the rail without
inclination, and then the stability of the vehicle is preserved.
