The superconducting electric levitation train achieves self-stabilizing levitation through the interaction between the induced current in the ground coil and the on-board magnet.The gap between the train and the track can be as large as 80~100 mm,making it suitable for high-speed operation.One of the key technologies of electric levitation transportation system is to accurately analyze the induced current in the ground coils and the electromagnetic force between the onboard magnets,to explore their impact on vehicle dynamics.This is the research goal of suspension force matching technology.To achieve the research objective,this paper conducted an analysis of the principle of suspension force matching and built a rotating test bench to complete the principle verification.Research was conducted on the matching calculation method for suspension force.Relying on high-temperature superconducting magnets,a 200 m-long electric suspension test line was built to verify the calculation method.Finally,the validated calculation method was applied to the design of a suspension force matching scheme for a high-temperature superconducting electric suspension transportation system with a speed of 600 km/h,followed by vehicle dynamics verification.Through the research,a set of matching calculation methods for suspension force of electric suspension systems applicable to different speed levels was proposed.The application and verification of the calculation method for high-temperature superconducting electric suspension transportation systems with a speed of 600 km/h were completed.The method can provide important theoretical support for the future engineering application of high-temperature superconducting electric suspension transportation systems.
