In this paper, we deal with the existence of infinitely many homoclinic solutions for the damped vibration problems ü ( t ) + A u ̇ ( t ) − L ( t ) u ( t ) + ∇ W ( t , u ( t ) ) = 0 , where A is an antisymmetry N × N constant matrix, we establish some new existence results to guarantee that the above system has infinitely many homoclinic solutions under more relaxed assumptions on W ( t , x ), which satisfies a kind of new subquadratic condition by using fountain theorem. Recent results in the literature are generalized and significantly improved. Copyright © 2013 John Wiley & Sons, Ltd.
