减少制动距离对提高铁路系统的安全性十分重要。然而,通过增加制动力来达到这个目的往往会在湿滑的条件下引起车轮滑动,因为车轮踏面和轨道之间的黏着力控制制动性能。针对这一问题提出了许多解决办法,包括“防滑(防锁)制动系统(ABS)”、“轮滑保护系统(WSP)”等等。文章介绍了高级的WSP系统,使用新的算法来检测车轮滑动以达到更高的性能,并通过线路测试证明所提出方法的有效性。
Reduce the braking distance to improve the safety of the railway system is very important. However, achieving this by increasing the braking force tends to cause the wheel to slip under wet conditions as the adhesion between the wheel tread and the rail controls the braking performance. A number of solutions to this problem have been proposed, including “Anti-skid braking system (ABS)”, “Skating protection system (WSP)” and many others. The article introduces the advanced WSP system, uses a new algorithm to detect wheel slip for higher performance, and proves the effectiveness of the proposed method through line testing.
