摘要
对抗侧滚扭杆如何影响地铁车辆车体限界进行分析。从限界标准公式入手,分析抗侧滚扭杆刚度如何参与限界计算。以国内某A型地铁辆为研究对象,采用现阶段3种常用的限界计算方法开展限界分析,对比研究抗侧滚扭杆刚度与车辆限界变化的规律及不同方法下的差异。采用动力学模型,以风压变化为条件,通过比对分析,提出抗侧滚扭杆刚度的取值范围建议。
The article analyses how the anti-roll bar affects the carbody clearance of subway vehicle. It starts from the standard clearance formula,analyzing how the anti-roll bar stiffness is involved in clearance calculation. It then takes a domestic Model-A subway vehicle as the object of study,analyses the clearances based on the existing three commonly used clearance calculation methods,making a comparative study on the vehicle clearance rules regarding the anti-roll bar and differences based on different methods. It finally adopts a dynamic model,takes the wind pressure variation as the conditions and rationally proposes the value range of anti-roll bar stiffness by making a comparative analysis.
