工程中的振动系统是其输入输出关系必须用微分方程描述(即现在输出与过去输入有关)的动态系统。系统的特性参数决定了输入和输出的转换关系。最原始的特性参数为物理参数即惯性质数(如质量)、弹性参数(如刚度)和阻尼参数。由物理参数导出并使用在各种不同场合的参数有很
The vibration system in a project is a dynamic system whose input-output relations must be described by differential equations (ie the output is now related to past inputs). System characteristic parameters determine the conversion relationship between input and output. The most primitive characteristic parameters are the physical parameters ie inertial mass (eg mass), elastic parameters (eg stiffness) and damping parameters. Derived from the physical parameters and the parameters used in a variety of different occasions
