摘要
通过一个振动模型的实验,研究一个单自由度振动系统的输入及输出。建立系统方程并通过拉普拉斯变换后,在频域中,研究属于频率响应函数范畴的三种概念,即动态柔度、迁移率和加速性。最后总结出这三种频率响应函数在实验里的应用范围。
A single degree of freedom （SDOF） system is studied through a vibration experiment. The systemequation is established and Laplace Transformation is taken. Then, dynamic flexibility, mobility and accelerance are discussed in order to get the goodness and application of these three kinds of frequency response.
