摘要
由受电弓的非线性运动微分方程通过泰勒级数展开得到垂向动力学线性化运动微分方程及模型,并得出等效参数的函数表达式。以国产SS7型机车的受电弓为算例,对弓头纵向几何运动、升弓力矩、受电弓等效参数、弓头运动最大加速度等进行了分析。
The linear motional differenfial eguation and model of the vertical dynamics is obtained by the expansiveness of the Taylor series from the nonlinear motional differential equation of the pantograph. Then the function expression of the equivalent paraemeters are established. Based on this, the analyses of the civil SS7 pantograph, such as the longitudinal geometry motion of the head, the torque of lifting pantograph, the equivalent parameters, the maximum acceleration of the head, are dealt with.
