地铁动车粘着系数的计算

Calculation of Adhesion Factor for Metro Motor Vehicle

为了较好地发挥车辆的牵引、制动性能,需要较合理地选择轮轨间粘着系数取值,从而使车辆处于较有利的粘着利用状况。从地铁列车的运行特点出发,提出电传动地铁动车计算粘着系数的计算要考虑大加、减速度的影响,并提出了具体的计算公式。

For better use of the traction and braking characteristics of mntro vehicle, the value of the adhesion factor between the wheel and rail should be selected reasonably, so that the vehicle is under a favorable utilization of adhesion. Slatting from the running characteristics of the metro vehicle, it is proposed that influence of acceleration and deceleration should be considered for the calculation of adhesion factor of metro motor vehicle. The calculation formula is also given.
