| 摘 要： | 对有轴箱自由间隙的反对称机车进行了空间耦合的非线性动力学仿真 ,指出轴箱自由间隙使得稳定机车有一定幅度的蛇行运动 ,也使得接近失稳的机车运行品质大幅下降 ,而且机车的静力反对称布置也是其横向振动的激励源

| Abstract: | System dynamics simulation experiments were done with a spatially coupled nonlinear model of an antisymetric locomotive,which has axle box clearance.It is pointed out that axle box clearance makes a stable vehicle have snake motion to an extent,and as well makes a uearly instable vehicle degrade substantially.Moreover,the statics antisymetric layout of locomotives is also exciting source of oscillation besides the track random and step geometric inputs. |
