“…But with the development of high-power locomotives, the mounting space occupied by the linkage rod restricts the size of the intermediate wheelset motor; this can only be resolved by introducing the forced-steering bogies. However, the existing forced-steering bogies 3 need further improvement before being used with locomotives since these bogies have a motor and gearbox, which makes their structure more complex than the other bogies.…”

In this paper, the design concept of a new type of asymmetric forced-steering bogie has been proposed. This bogie is supposed to produce a better curving performance than the self-steering bogies and is well suited for mounting on locomotives that have limited bottom space. Schemes A and B, the only feasible schemes for vehicles with two bogies, were adopted and compared with the self-steering bogies. SIMPACK,the dynamics simulation software, was used to establish the dynamics models of the locomotives. The lead wheel angle of attack, lead wheel lateral force, lead wheel wear power, and the total vehicle wear power were compared and analyzed when the three different bogies negotiate the curves. The results showed that the performance of the locomotives is closely related to the layout of the front and rear asymmetric forced-steering bogies; in scheme A, where the front and rear bogies are antisymmetrically placed, curve negotiation performance was excellent and notably superior to the self-steering bogies-especially on curves that have small and medium radius. Under the traction condition, the total vehicle wear power in scheme A can be reduced by up to 24.6% compared to the locomotives of the self-steering bogies. An experiment on an S-shaped curve has proved that the angle of attack and total vehicle wear power of all the three schemes retained the symmetrical dynamics performance.

“…A type of bogie angle linked steering truck which steers the wheelsets depending on the relative yaw angle between the car body and the truck is able to significantly reduce wheel lateral forces when passing through a curve [1]. However, the problem with this system is that the reducing effect on wheel lateral forces is smaller in transition curve sections than in circular curve sections because the steering device specifications are determined by its geometric shape in a circular curve.…”

“…Forcedsteering traction bogies are uncommon. One example is the two axle DC283 bogie of Hokkaido Railway Company which has operated on a limited express train since 1997 [8]. Passive steering bogies have been shown to have deteriorated steering when operating traction forces are high [7,9,10].…”

Active steering control in the form of secondary yaw control (SYC) and actuated wheelset yaw (AWY) have been in prototype development. This paper presents a new active steering bogie design, actuated yaw force steering (AY-FS), that is able to steer under high traction loads in tight curves. The AY-FS bogie design is compared with the AWY design. The steering performance AWY under high traction loads has not been previously reported. This paper examines five control methods, three for AWY and two for AY-FS bogies and assesses the traction curving and stability control performance of the alternative designs and control methods compared with each other and to passive steering bogie designs. The curving performance results showed considerable advantage in the proposed AY-FS bogies over the AWY. It was shown that control must be applied to both the yaw angle and the steering angle of the bogie to achieve the best traction steering performance which was not possible with the AWY bogies. The proposed new bogie designs of AY-FS overall give better traction curving and stability performance than the AWY designs.
