Influence of Polygonal Wheels in High-speed Trains on Dynamic Performance of Turnout

doi:10.3901/JME.2018.04.047

Abstract

Abstract: In order to analyze the effect of polygonal wheels on the dynamic performance of the vehicle through the turnout, the high-speed vehicle-turnout coupling model is built based on the high-speed train and No. 12 turnout in passenger dedicated line. The polygonal wheels are modeled with the harmonic and measured radius deviations. Considering the status of polygonal wheels through the turnout, the distribution, order and amplitude of polygonal wheels, the wheel-rail dynamic interaction is calculated. The results show that the maximum response occurs when the point on the wheel with the maximum radius deviation rate passes the nose rails. When the order is less than 15 and 16, the dynamic response will be increased with the increase of the order, and it will be decreased when the order is bigger than 15 and 16. The dynamic response for the same-phase polygons on both sides of wheel set is bigger than that for the inverse-phase. The wheel-rail vertical force and vertical acceleration of wheels will be increased with the increase of the amplitude. The wheel-rail vertical force would exceed the safety limit if the amplitude reaches 0.20 mm. When the amplitude is bigger than 0.16 mm, the dynamic response will be increased significantly. The polygonal wheels have little effect on the vehicle riding stability.

Key words: high-speed railway, polygonal wheels, turnout, wheel-rail system dynamic, wheel-rail vertical force
