Conceptual design of an active centre plate

  • The efficiency and safety of railway transportation depend both on numerous factors linked to the vehicle, the infrastructure, the operator and the environment. Curved tracks are subjected to demanding situations due to elevated stress levels, as a function of the operating conditions and vehicle/infrastructure design. In such segments, steering forces are superimposed to lateral load transfers. The steering forces depend on the condition and the design of the centre plate and bogies’ suspensions design. While the friction at the centre plate provides the needed damping to mitigate the hunting vibration of the bogie in straight track segments, such yaw resistance originates high steering forces and rail damage on curved tracks. A centre plate with low friction at turns and high friction at straight track segments would thus be highly advantageous. In this paper, a centre plate design is proposed which provides a yaw-rotation resistance torque that depends on the bogie-car relativeThe efficiency and safety of railway transportation depend both on numerous factors linked to the vehicle, the infrastructure, the operator and the environment.

A centre plate with low friction at turns and high friction at straight track segments would thus be highly advantageous. In this paper, a centre plate design is proposed which provides a yaw-rotation resistance torque that depends on the bogie-car relative position. Two different designs are considered for that purpose, one that combines a spring-acted centring mechanism with a lower pair kinematics, while the other one involves higher kinematic pairs which should incorporate lateral damping elements. As a result of using an engineering design approach, the higher kinematic pairs-based design is recommended however, the validation of such operational principles, including the introduction of the needed damping, should be configured on the basis of experimental models.zeige mehrzeige weniger
