摘　　要：从工程应用角度分析了最简单的机械结构（单摆）的全局运动，包括简谐振动，非谐振动，界轨，连续旋转，衰减振动，受迫振动，周期倍化及混沌振动，展现了线性振动及非线性振动在全局运动中的地位，介绍了混沌振动及周期倍化通道．From the point of view of engineering application, this paper analyses the global motion in the most simple mechanism( i. e. simple pendulum), including harmonic vibration, non-harmonic vibration, critical orbital motion, continuous rotation, decreasing vibration, forced vibration, period- doubling and chaotic vi-bration. The status of linear vibration and non- linear vibration in the global motion, chaotic vibration and its way of period doubling are introduced.

关 键 词：单摆 全局运动 混沌振动 简谐振动 非谐振动 周期倍化通道
