| 摘 要： | 用支撑超平面法分析了多自由度振动系统对积分能界界限凸集荷载荷的响应，导出了时间上限为有限和无限两种情况下可达集的边界方程。最后给出了一个实例，得到了不同积分上限时的响应可达集，并将凸集响应与谐波响应及非平衡随机响应作了对照。

| Abstract: | A support hyperplane method is used to analysis the response to the excitation modeled byintegral energy-bound convex set. An analytical expression is obtained for the boundary equation of the fi-nite-time and infinite-time response reachable set- An example is given to obtain the response reachablesets at different instants, and the comparison for a convex response with a harmonic response and a non-stationary random response is also done. |
