电动客车，如由电动动车组组成的通勤列车，在人口众多的城市中是非常有用的公共交通。为了实现高效的大规模运输，需要通勤列车具有较高的加减速性能，而切向力系数是由轮轨切向力与列车轴重之比定义的，它是轮轨滑移速度的函数，在滑移速度很小时有最大值。切向力系数的最大值称为附着系数，它是切向力系数与滑移速度之间的特性的峰值。滑移速度的增加导致切向力系数单调减小。滑移速度向零方向减小也会导致切向力系数减小。粘附系数强烈地受c ...更多信息 当钢轨与驱动轮之间的粘着系数减小时，驱动轮的滑移速度大于其最大值。然后，电动火车有打滑现象。打滑现象严重影响了电动列车的乘坐舒适性。此外，它导致切向力系数进一步减小，并且电动列车具有对轨道和驱动轮的消耗。因此，要求电动通勤列车的驱动系统具有良好的防滑与再附着控制系统，为了克服这一问题，本研究提出了一种基于干扰观测器的新型防滑再附着控制系统。所提出的系统具有良好的转矩响应的四个驱动轮由四个感应电机驱动，只用一个逆变器。本文所提出的方法的有效性已经通过试验和数值仿真得到了验证。在本研究中，我提出的方法应用到实际的电动动车组，这是东日本铁路公司的205-5000系列。在205-5000系列的实验结果中，本研究讨论了所提出的防滑/防滑再附着控制系统具有期望的驱动轮扭矩响应和期望的防滑控制性能。此外，本研究还探讨了再附着控制试验结果的评价方法。少

Electric motor coaches, such as commuter train composed of electric multiple units, are very useful for mass transportation in the large population city. A high acceleration and deceleration performance of the commuter train is needed for realization of efficient mass transportation.The tangential force coefficient is defined by the ratio of the tangential force between rail and wheel to the axle weight of electric train, and it is a function of the slip velocity of wheel to rail, which has maximum value at a very small slip velocity. The maximum value of the tangential force coefficient is called the adhesion coefficient, which is the peak value of the characteristics between the tangentiall force coefficient and the slip velocity. Increase of the slip velocity from leads to monotonous reduction of the tangential force coefficient. Decrease of the slip velocity toward zero also causes reduction of the tangential force coefficient. The adhesion coefficient is strongly affected by the c … More onditions between rails and driving wheels, such as a drop of water, dust, oil on the rail and so on. When the adhesion coefficient between rail and driving wheel decreases, the slip velocity of the driving wheel becomes greater than its maximum value. Then, the electric train has a slip phenomenon. A slip phenomenon degrades the comfortable riding performance of electric train. Moreover, it leads to further reduction of the tangential force coefficient, and the electric train has a consumption of both the rails and the driving wheels. Therefore, the driving system of electric commuter train is requested to have a fine anti-slip and anti-skid re-adhesion control system.In order to overcome this problem, this research proposes a new anti-slip re-adhesion control system based on disturbance observer. The proposed system has the fine torque response for four driving wheels driven by four induction motors using only one inverter. However, the effectiveness of the proposed method has been confirmed by the experiment and the numerical simulation using the tested bogie system of electric train, whish is not an actual train system. In this research, I applies the proposed method to the actual electric multiple units, which are Series 205-5000 of East Japan Railway Company. In the experimental results of Series 205-5000, this research discusses that the proposed anti-slip/skid re-adhesion control system has the desired driving wheel torque response and the desired anti-slip control performance. Moreover, this research discusses the evaluation method of re-adhesion control test results. Less
