摘要:
为分析中低速磁浮车辆在直线段上 2 种不同磁轨关系的动力学性能的差异,分别采用弹簧阻尼法和悬浮控制法建立磁轨关系模型,分析 2 种磁轨关系力学特性,对采用 PID 控制的悬浮控制法的悬浮刚度和阻尼进行等效处理,并转换成弹簧阻尼法中的线性刚度和阻尼。通过仿真分析发现: 2 种模型在直线段的垂向平稳性、 车体和构架的垂向加速度相差很小,有相近的计算精度; 悬浮力最大值和 3б 统计值相差很小,均不超过 0.2kN。因此,在计算中低速磁浮车辆直线动力学性能时,弹簧阻尼模型可以替代悬浮控制模型。
Abstract:
In order to analyze the difference of dynamic performance between two different kinds of maglev tracks on the straightline of a medium-low speed maglev vehicle, the spring damping method and the suspension control method were used to establishthe relationship model of the maglev tracks, and the mechanical characteristics of the two kinds of maglev tracks were analyzed. Thesuspension stiffness and damping of the suspension control method controlled by PID were treated equivalently and converted intolinear stiffness and damping in spring damping method. Through simulation analysis, it was found that the vertical stationary of thetwo models in the straight line segment, the vertical acceleration difference between the car body and the frame is very small, and thecalculation accuracy is similar; the difference between the maximum suspension force and the 3б statistic value is very small, and thedifference is not more than 0.2 kN. Therefore, the spring damping model can replace the suspension control model in calculating thelinear dynamic performance of medium-low speed maglev vehicles.
