1.前言轮轨间的粘着是限制机车性能发挥的极其重要的因素,尽管以前对它进行过大量研究,但至今仍有许多问题未搞清楚。而且,过去的研究,又大都是关于新干线200km/h以上的高速区,主要是电力动车粘着性能的改善,以及为了提高电力机车粘着时牵引电动机的控制等方面的,而有关内燃机车方面的粘着研究却不 1. Introduction The adhesion between wheels and rails is an extremely important factor that limits the performance of locomotives. Although many studies have been conducted on it before, many problems still remain unclear. Moreover, in the past, most studies focused on the high-speed zone above 200km / h on the Shinkansen, mainly on the improvement of the adhesion performance of electric vehicles and on the control of the traction motors for adhesion of electric locomotives. However, Adhesive research is not
