... the bearing adapter and pedestal roof. The secondary suspension, which includes the friction wedge and load coils, connects and provides damping on each end of the bolster at its intersection with the side frame. Moreover, the friction wedge aids in warp resistance of the bogie. Because of the wedge’s non...

... This paper presents an effort to use multi-body dynamics with unilateral contact to model the friction wedge interaction with the bolster and the side frame. The new friction wedge model is a 3D, dynamic, stand-alone model of a bolster-friction wedge-side frame assembly. It allows the wedge four...
