I think it should be much clearer that there is really no difference between the time domain, frequency domain, modal space and physical space. Each domain is just a convenient way for presenting or viewing data.
时域-频域-模态空间和物理空间: 用于观察系统振动的不同视角. 文中的图解简介易懂. 首次提到振动矩阵方程, 求解矩阵, 将耦合系统解析为各个自由度系统的集合. 这就是运用矩阵的魅力.
So often we transform from one domain toanother domain simply because the data is much easier tointerpret.
哪一个个"视角"易于观察系统, 就使用哪一个.
- April 98 Could you explain the difference between the time domain, frequency domain and modal space?
