A support hyperplane method is presented to find the response set defined for a linear time invariant vibration system under the excitations modeled by some convex sets. 对激励由凸集合建模的线性振动系统提出了响应集的概念，将数学上的微分包含问题简化为求解多自由度振动系统的响应集问题。
The response of a two-degree-of-freedom vibro-impact system under stochastic excitation can be obtained by using stochastically excited and dissipated Hamiltonian system theory. 本文应用随机激励的耗散的哈密顿系统理论研究了二自由度碰撞振动系统的随机响应。
