25T型提速客车密接式钩缓装置运用问题的解决

The Solution of Problems in Operation of Tightlock Coupler Draft Gears on 25T Speed Increased Passenger Cars

通过从设计计算、疲劳试验、生产工艺、线路动力学测试等各方面开展的研究,找到了密接式钩缓装置投入运用初期曾出现的钩尾销强度裕量不足现象的原因,并提出了有效的解决措施。

Through the research carried out in such aspects as the design calculation, fatigue test, production technology, dynamics testing on track, the causes to insufficient margin of coupler yoke strength appeared in the initial stage of operation of the tightlock coupler draft gears are found out, and effective measures for solution are put forward.
