测量结构物自振特性的方法很多，主要有稳态正弦激振法、传递函数法、脉动测试法和自由振动法。实际工程结构比较复杂，难以完全在数学模型中得到反映，影响到结构动力特性求解的精度。因此，选择重要途径也是校核各种数学模型和各种简化公式的重要手段。

There are many methods of measuring the vibration characteristics of the structure, mainly including the steady si-ne excitation method, the transfer function method, the pulse testing method and free vibration method. The practical engin-eering structure is more complex, difficult to completely refl-ect in the mathematical model, af ecting the structure dynamic characteristics calculation accuracy. Therefore, selecting an i-mportant means of selection is also an important way to check various mathematical models and various simplified formula.
