| Abstract: | This paper is dedicated to study the periodic solutions for a class of damped vibration problems.By virtue of auxiliary function,we obtain some kinds of new superquadratic growth and asymptotically quadratic growth conditions.Using the minimax methods in critical point theory,we establish some existence results,which unify and generalize some known results in the literature. |

| Keywords: | Minimax method Asymptotically quadratic Superquadratic Periodic solution |
