摘要/Abstract

摘要： 建立常导高速电磁悬浮车辆系统动力学模型,模型详细考虑了电磁悬浮系统、控制系统电动力特性、悬挂系统的非线性特性。传统高速电磁悬浮车辆为摇枕+空簧+吊杆结构,其结构复杂,制造、维护成本高。探索性提出取消传统摇枕,采用大变位空簧直接支撑车体的二系悬挂方案,并进一步研究无摇枕增设抗侧滚扭杆的二系方案。基于车辆系统动力学模型,从车辆运行平稳性,曲线通过性能等角度,对三种二系悬挂配置下的车辆动力学性能进行对比分析。得出以下结论:有摇枕方案的各项动力学指标均较优于无摇枕方案;相对于无抗侧滚的二系结构,有抗侧滚的车辆车体横向、垂向及侧滚角位移均有所降低,并且已经达到了与有摇枕方案基本相当的水平;无摇枕增设抗侧滚结构的二系悬挂方案能够达到简化车辆悬挂系统结构的效果,同时能够满足动力学性能要求,推荐在日后的结构设计中采用该方案并进行试验验证。

Abstract: The dynamic model of high-speed EMS train is established considering the electromagnetic levitation system, the electro dynamic characteristics of the control system and the nonlinear characteristics of the suspension system. The secondary structure of traditional high-speed EMS train is complex and high cost with bolster, air spring and suspender. A new secondary suspension scheme using air spring which adapted to large displacement to support the car body directly and canceled the bolster is carried out exploratively. The secondary scheme of adding anti rolling bar without bolster is further studied. Based on the dynamics model of vehicle system, the vehicle dynamic performance under three kinds of secondary suspension is analyzed and compared aiming at the running stability and the performance of curve passing. The conclusions are as follows. The dynamic performance of the scheme with bolster are better than those without bolster. The lateral, vertical and roll angle displacements of the vehicle body with anti roll bar are reduced compared with the secondary suspension without anti roll, and reached the level of the scheme with bolster. The secondary suspension scheme without bolster adding anti roll bar is recommended to adopt in future structural design and carry out test verification which can simplify the structure of secondary suspension system and meet the requirements of dynamic peformance.
