Abstract	For Analysis of curve-running performances and influencing factors of maglev guidance system. This paper is based on double bogies system and investigates influences of pendulum-structure when system running on the curve. Firstly, system structure and simplification conditions are described. Secondly, dynamics model of carriage and kinematics model of bogies have been set up. Thirdly, formulas of movement and pulling forces of pendulums have been deduced. Finally, system simulation has been realized by Matalab/simulink and acquired function curves of pendulums at different running speed. Moreover, according to curves of simulation and testing, influence of pendulums on guidance system has been analyzed and obtained regulation of guidance currents. Results indicate forces of pendulums acting on bogies are relative to running speed and railway parameters, composition of moments is a constant nearly 3KN.m on circular curve of radius 400m, which makes bogie I revolve clockwise and bogie II revolve anticlockwise, then guidance currents are compensated along diagonal of bogie for supplying electromagnetic forces. Change trend of currents by simulation analysis basically coincides with testing curves, and when running speed is overhigh and guidance currents are not increased in time, guidance gaps close to inner curve and at both ends of system will be decreased faster, which maybe cause collisions of guidance magnets and guideway and the positions are corresponding with testing phenomenon. The conclusions show that system model is reasonable and the results are valuable for betterment of guidance controller and curve negotiation capacity and analysis of the whole maglev train.
