Analysis on dynamics characteristics of a newly mid-low speed maglev train model
This paper focuses on analyzing the dynamic characteristics of a newly designed mid-low speed maglev frame,capable of running at speeds up to 160 km/h,using a train dynamics model established by SIMPACK multi-body dynamics analysis software,un-der both straight track and curve conditions.The results showed that the train reached 160 km/h under the straight track condition,while meeting the required levitation gap,carbody vibration acceleration,and other performance indicators.However,the performance indica-tors of the train deteriorated at 120 km/h.A frequency analysis was conducted specifically on carbody vibration acceleration,leading to optimization suggestions aimed at mitigating the impact of carbody resonance.Furthermore,under the curve condition,the train parame-ters including guiding force,lateral displacement of the air spring,and sliding table displacement all remained within the normal ranges.The study findings demonstrate the compliance of this newly mid-low speed maglev train with the requirements of the dynamics perfor-mance.The relevant dynamics results can provide data support for the follow-up research and subsequent engineering applications of this maglev frame.
