Abstract Research purposes: By using solid design software，ADAMS software and the multi-body dynamics theory， solid model and dynamics model of the steering mechanisms of low velocity maglev trains have been developed. The stylized simulation platform developed can predict dynamic characteristics of low velocity city maglev trains in many typical conditions and can lay theory analysis foundation for the structure parameters design and optimization.
Research conclusions:(1)Compared with the results of the traditional analytical method in many typical conditions，a high accuracy and reliability multi-body model of the steering mechanisms of a low velocity city maglev train with 87 degree of freedom has been built. The model can simulate dynamic response characteristics of the system under various special conditions which can not be calculated accurately by the traditional analytical method.(2)Virtue no mass moving 5 planets which contour maglev railway are created in the model.(3)Non-linear air-springs，non-contact maglev force elements and railway constraints are expressed in the built model.(4)The stylized simulation model developed in this paper is more suitable for parameter optimization design of the steering mechanisms and can be meaningful to the virtue platform of low velocity city maglev trains which will be created in the future.
