Superconducting magnetic levitation (maglev) is developing rapidly in recent decades for its incomparable features like ultrahigh cruising speed. To develop the second generation high tempera-ture superconducting (2G HTS) maglev, a serious of work has been done by us including design of propulsive system, optimiza-tion of 2G HTS magnet system, energizing tests and over-current duration tests. In this work, as a continuation of the development progress, mechanical properties of the on-board 2G HTS magnet system that used in the maglev are evaluated, including modal analysis, harmonic response, random vibration, and shock response. Meanwhile, bench tests under much severer mechanical conditions are conducted, resulting no damages of the magnet. This work is intended to not only evaluate the mechanical properties of the magnet system, but also provide possible references and methods for similar mechanical assessment of other superconducting apparatuses.
