A finite-element simulation that solves the electromagnetic force of a maglev train when the magnetically permeable medium is saturated is very time-consuming. The existing analytical formula for the two-dimensional magnet-rail relationship assumes that the magnetic medium operates in the linear regime of the B-H curve, which does not apply in the case of magnetic saturation. To address these shortcomings,...
While running on the track, mid-low speed maglev has to deal with the disturbance from Guideway steps and gaps, which may bring impulse to the suspension system. In order to suppress the influence of the guideway gaps to the vehicle, enhance the reliability of the system and bring passengers comfort, the article puts forward a compensation algorithm, which judges the guideway steps according to the...
Modeling is the basis work of the analysis and design of a control system, and models obtained by different modeling methods have different characteristics. In the maglev system, current is generally used as a state to model. Through analysis and comparison in this paper, compared with modeling with current state, using magnetic flux density as a state to model the maglev system, the model is much...
Aiming at analyzing the vibration and the vibration inconsistent of CMS04 Maglev in guideway step disturbance during the running in Tangshan test line, this article builds the suspension model of double point in one bogie and analyzes its open-loop instability in theory. Gap-current double loops cascade control strategy is also used to simulate and analyze the dynamic process of model passing guideway...
