Abstract: In this paper, we are concerned with the problems of the existence and multiplicity of symmetric periodic solutions with impact for a class of weakly coupled systems of two degrees of freedom with obstacles. Under some superlinear assumption on time-mapping, the existence of infinite symmetric harmonic solutions with impacts and symmetric subharmonic solutions with impacts of the equation is proved.

Key words: symmetric equations with obstacles, weight functions, symmetric periodic solutions with impacts, time-mapping, Poincare mapping
