中低速磁浮车辆悬浮架抗侧滚吊杆解析与有限元分析

Anti-roll Steeves Parsing and Finite Element Analysis of Medium and Low Speed Maglev Vehicle Suspension Frame

综合考虑中低速磁浮车辆悬浮架抗侧滚片梁和吊杆的刚度,通过解析分析和动力学仿真研究了抗侧滚吊杆刚度对悬浮架扭转刚度、悬浮电流和悬浮模块侧滚角的影响。解析分析表明,采用刚性吊杆和弹性吊杆时,悬浮架的抗扭刚度大小基本一致;但采用刚性吊杆,悬浮模块的侧滚角明显小于采用弹性吊杆的侧滚角。动力学仿真计算显示,当磁浮车辆通过曲线时,采用弹性吊杆时电磁铁电流波动幅值较小,但电磁铁发热量变化并不明显。

Comprehensively considering the stiffness of anti-roll beams and steeves of medium and low speed maglev vehicle suspension frame,the influence of anti-roll steeves stiffness on the suspension frame torsion stiffness,on the levitation current and suspension module roll angle is studied by analytical analysis and dynamic simulation.The analytical results show that the torsion stiffness of the suspension frame is generally the same while rigid steeves and elastic steeves being adopted respectively.But when rigid steeves are adopted,it is evident that the roll angles of the suspension modules are smaller than that with the elastic steeves.The dynamic simulation calculation results show that when the maglev vehicle is passing curve,the current fluctuation value of the electromagnet coil is small when the elastic steeves are adopted,but the heat generation of electromagnet coil is not obvious.
