Experimental assessing of the rail forces due to bogies´ centre plate friction

  • The magnitude of the steering forces at the wheel-track Interface depends on different properties and operational conditions linked to the vehicle and to the track, with the bogie´s yaw stiffness/resistance and the friction at the centre plate being recognized as the most influential vehicle factors. In this respect, the negative consequences of high values for yaw resistance have been recognized in terms of the railway accelerated deterioration and on the possibility for derailment. While some theoretical models have been proposed to simulate the effects of the centre plate friction on the railway damage, and experimental measurements have been reported of the turning resistance, no experimental data is available regarding the effect of the friction at the centre plate on the wheel-track forces. In this paper the conceptual design of a testing rig is presented for assessing such forces as a function of the center plate friction.

In this paper the conceptual design of a testing rig is presented for assessing such forces as a function of the center plate friction. The testing rig quantifies the effects of the friction forces developed at the centre plate, in terms of the loss of potential energy when a scaled-down vehicle travels downwards and tries to return upwards in a “U turn” maneuver. A simplified mathematical model is also proposed in this paper, whose Outputs suggest a significant effect of the dry friction on the magnitude of the steering forces.zeige mehrzeige weniger
