摘　　要：考虑一类具有两个自由度的弱耦合对称碰撞方程的对称碰撞周期解的存在性、重性问题.在一类关于时间映射的超线性条件下证明了方程无穷多个对称碰撞调和解和对称碰撞次调和解的存在性.同时,还给出了一个适合两个自由度的对称碰撞方程的对称碰撞周期解存在的充分条件.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 are concerned.Under some superlinear assumption on time-mapping,the existence of infinite symmetric harmonic solutions and symmetric subharmonic solutions with impacts of the equation are proved.Furthermore,a sufficient condition for the existence of even and periodic bouncing solution is given for the coupled symmetric impact equations of two degrees of freedom.
