Analysis of Curve Negotiating Performance of Asymmetrical Radial Bogies
摘要
Abstract
A new scheme for asymmetrical radial bogies is proposed. Mechanical properties and steering principles of the asymmetrical radial bogies are analyzed. Dynamics models of symmetrical bogies, asymmetrical radial bogies and normal bogies are built respectively by means of Simpack. Curve negotiating performance of the asymmetrical radial bogie when the train passing through left and right curves is analyzed respectively. The utilization ratios of adhesion on curves of the three bogie models are calculated. And the influence of the traction forces of the three models on curve negotiating performance is investigated. The results indicate that the asymmetrical radial bogie has a good symmetry of performance when negotiating both left and right curves. Both symmetrical and asymmetrical radial bogies have essentially the same utilization ratio of adhesion when running on the dry and slippery curved tracks. However, on dry curved tracks with the radius less than 700 m , both adhesion utilization ratios of the two radial bogies are greater than the one of the normal bogie. With the increase of the curve radius, the yaw angle of the first wheelsets of the two radial bogies and the lateral force of the rear wheelsets are smaller than the one of the normal bogie. Derailment coefficient and wear power of whole vehicle with normal bogie are greater than the one with the two radial bogies when running on the curved track with various radii. It can be concluded that the asymmetrical radial bogie possesses the same good dynamics performance as the symmetrical radial bogie, and is better than the normal bogie.关键词
