Abstract
This paper discusses stability and performance of a full-train system employing inerters. First, a twenty-eight degree-of-freedom (DOF) train model was built on AutoSim^<TM> and linearized for analysis in Matlab^<TM>. We then optimized the critical speed of the system and showed that the critical speed can be significantly improved by employing inerters. Third, we discussed the system's transient responses and illustrated that the settling time can be greatly shortened by using inerters. Lastly, a novel mechatronic inerter was considered for further improvement of the train system.
