Abstract：Research purposes ： In our country under the background of new construction of medium and low speed maglev operation，because the low speed maglev rail beam is relatively light， in order to ensure the safety and comfort， the maglev train - track beam coupling vibration should be analyzed and verified. Based on the engineering background of 20 m simply supported beam of maglev test line in a factory of Zhuzhou，this paper establishes the secondary suspension quality - spring - damper model that vehicle is 12 degrees of freedom， builds maglev trains and track beam vertical coupling vibration analysis model considering the impact of track irregularity，and designs the simulation analysis software VTBIM. Through comparing the simulation value with the measured values，the rationality of the model is verified.
Research conclusions ： (1) Test the fundamental frequency，vibration mode and span dynamic deflection / acceleration of the beam， and the fundamental frequency and vibration mode test results are slightly smaller than the simulation values. (2) When maglev vehicles go through the simply supported beam， the measured values of span dynamic deflection / acceleration of the beam are slightly smaller than the simulation values，the theoretical simulations variation law with the speed is consistent with the measured law，time - history curve of the deflection is consistent with the measured curve. (3) The vertical model of the medium and low speed maglev train - track beam coupling vibration which is built in this paper is reasonable, the result of simulation program in this paper is effective. (4)The result can
be applied to medium and low speed maglev track beam design.
