高速列车最优黏着控制方法研究及展望

A Research and Prospect of Optimal Adhesion Control Method for High-speed Train

为了使实际的黏着系数尽量逼近于当时路况的黏着系数最大值,以获得更大的平均牵引力,提高黏着利用率。在介绍轮轨黏着机理的基础上,总结了高速列车基于最优黏着的空转判据和相应的黏着控制方法,详细介绍了各种方法的理论基础和优缺点,最后对我国黏着控制的发展作了展望。

In order to make the actual adhesion coefficient as close as possible to the prevailing viscosity coefficient at the time,in order to obtain greater average traction,improve the adhesion utilization.On the basis of introducing the mechanism of wheel and rail adhesion,the paper summarizes the idling criterion of the high speed train based on the optimal adhesion and the corresponding adhesion control method.The theoretical basis and advantages and disadvantages of each method are introduced in detail.Finally,the development of adhesive control in China is forecasted.
