The Noether symmetry of vehicle vibration systems with electromagnetic suspension was studied,and the conserved quantity of the system was given. Furthermore,with the conserved quantity,the symmetry solution of the system was obtained. In the form of energy,the Lagrangian equations under different vibration modes were built. With the chosen displacement coordinates as the generalized coordinates,the Noether symmetries of the system under different vibration modes were studied,the corresponding Noether ident...
