| Abstract: | Based on the thoughts of wheel and track coupling big system, rails were simplified as a Euler-beam with limit length by a springy point, and contact relation between wheel and rail was treated as spring contact, it was established dynamics model between wheel and rail. And when wheels were running at homogeneous speed, vertical vibration response of interaction between wheel and rail under excitation of dipped joint signal was outputted. And dipped joint influence to raise train speed was also presented. |
