Abstract As an important bearing structure of maglev train, the connecting rod has high requirements for material performance. In this paper, according to structural capacity rod, finite element methodwas used calculate and analyze composite aluminum alloy under two working conditions, so as determine advantages in mechanical properties provide theoretical support design rod.
