摘　　要：阻尼振动在物理学中是一类重要的振动类型,形式复杂多样。以弹簧振子为例,运用Mathematica软件计算模拟阻尼振动,并且对阻尼振动进行傅立叶分析,用图像直观展现阻尼振动的特性,帮助人们理解阻尼振动的原理和探究阻尼振动的基本规律。研究为相关的教学研究和工程分析提供了有益借鉴。In physics,damped virbaration is an important class of virbaration with diversified complex forms. In this paper,taking the spring oscillator as an example,we employ Mathemaitca to caluclate and simulate the damped virbaration. We further analyze the virbation by fourier analysis method and vividly present the features in figures. This is helpful to understand and explore the principles and discipline of damped force. Additionally,our studies provide a useful reference for relevant education research and engineering anlysis.
