    Abstract
  • Low-speed maglev train structures and kinematical relationships were analyzed, its dynamics model was developed by using multi-rigid-body dynamics modeling method, the movements of different components of secondary suspension in curve negotiation were analyzed, and the significance of parallelogram mechanism in curve negotiation was explained. Simulation result shows that parallelogram mechanism averagely distributes lateral forces among modules, so that modules are distributed reasonably along the curve. Parallelogram mechanism decreases the lateral and longitudinal forces of air spring, and the yawing angles of modules, which is helpful for curve negotiation and guidance. Speed influences lateral displacement to a certain extent, while the curve radius of the track is the major factor.
