ajst-5928	Dai, Yang; Ye, Chao	Influence of Wheel Polygons on Dynamic Performance of Trains	2023	5	.pdf	application/pdf	2787	109	50	Abstract: With the continuous development of high-speed railroad technology, the operating speed and mileage of moving trains continue to increase, and the phenomenon of wheel-rail contact fatigue and wear is gradually highlighted, and the problem of wheel polygon wear is also prevalent in the operating site. By analyzing the ICE-1 train model, Morys [4] concluded that the track structure and excitation frequency have a crucial influence on the order of wheel polygon wear, and that different travel speeds and different track characteristics dominate different orders of polygons.	cache/ajst-5928.pdf	txt/ajst-5928.txt
