本文提出了根据实验得到的传递函数识别振动系统物理参数的一种方法,其特点是计入了对于待识别参数的约束,并解决了数值计算传递函数时取点数目较大的困难。经算例考证,该方法对物理参数识别效果良好。
This paper proposes a method to identify the physical parameters of the vibration system based on the experimental transfer function. It is characterized by the constraint on the parameters to be identified, and solves the difficulty of obtaining a large number of points when calculating the transfer function. According to the calculation of the calculation example, this method has a good effect on the identification of physical parameters.
