Abstract: Comprehensively considering the stiffness of anti-roll beams and steeves of medium and low speed maglev vehicle suspension frame, the influence of anti-roll steeves stiffness on the suspension frame torsion stiffness, on the levitation current and suspension module roll angle is studied by analytical analysis and dynamic simulation. The analytical results show that the torsion stiffness of the suspension frame is generally the same while rigid steeves and elastic steeves being adopted respectively. But when rigid steeves are adopted, it is evident that the roll angles of the suspension modules are smaller than that with the elastic steeves. The dynamic simulation calculation results show that when the maglev vehicle is passing curve, the current fluctuation value of the electromagnet coil is small when the elastic steeves are adopted, but the heat generation of electromagnet coil is not obvious.
