| Summary: | 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. |
