| 摘 要： | 对中低速磁悬浮轨道梁设计和试验进行系统阐述。研究表明:中低速磁悬浮轨道梁适宜采用单箱单室后张预应力混凝土简支梁,强度计算不是轨道梁的控制因素,但是截面扭矩很大;刚度和动力性能成为中低速磁悬浮轨道梁的设计控制因素,通过试验,给出刚度和自振频率限值。专门研制的拉力调高钢支座能保证轨道梁横向稳定,预制架设方法是最适宜的施工方法。

| Abstract: | Design and test of medium/low speed Maglev track beams are summarized in this paper.Studies show that single box simple beam is suitable for medium/low speed Maglev track beams,while beam strength is not a control factor whereas torques are very large.Beam stiffness and dynamic performance are control factors for medium/low speed Maglev track beam design.Limiting values of stiffness and free vibration frequency are put forward according to the experiment.A kind of tensile height-adjustable bearing is develo... |
