AXLE-DRIVE DYNAMICS FOR HIGH RUNNING SPEEDS OF A DIESEL LOCOMOTIVE

LA DYNAMIQUE D'ENTRAINEMENT DE L'ESSIEU POUR VITESSES DE MARCHE ELEVEES D'UNE LOCOMOTIVE DIESEL

A study of the vibratory movement of the drive system using seven coordinates to define vertical displacement, angular direction and inertia moments in relation to their balancing position. From an analysis of the specific example of a locomotive driven independently by an electric transmission it has been possible to reach the following conclusions: a tangentially flexible wheel reduces dynamic stresses by 40 percent over rigid transmission; the flexible suspension of the engine reduces the torque whilst improving the rate of adherence; for speeds between 10 and 200 km/h, the maximum axle discharge value is virtually constant.
