新干线列车速度越来越高。但在下雨时车轮和钢轨问可能的粘着系数就会降低。对于300km/h以上的营业运行速度来说，为了有效地利用列车的粘着力和提高自身的粘着系数，技术上就必须有所突破。本文就最近的一些研究成果，介绍在现车上对粘着系数进行测试的实例以及有效利用粘着系数和增加粘着力的方法。在车轮和钢轨间喷射陶瓷粒子可以增加粘着，以防止车轮的空转和滑行。还介绍了利用陶瓷粒子增加粘着的机理及在现车上的试验结果。
Shinkansen train speed is higher and higher. However, when it rains, the possible adhesion coefficient between the wheel and the rail decreases. For more than 300km / h of operating speed, in order to effectively use the train adhesion and improve their own adhesion coefficient, technically must make a breakthrough. In this paper, some recent research results are introduced in the car on the adhesion coefficient test examples and effective use of adhesion coefficient and increase the adhesion of the method. Spraying ceramic particles between the wheel and the rail can increase adhesion to prevent the wheels from spinning and gliding. Also introduced the use of ceramic particles to increase the adhesion mechanism and in the car on the test results.
