| 摘 要： | 为了建立机械结构系统的动力学模型，提出了一种新的建模方法．本文重点研究了该方法中的两个基本部分：（1）根据结构响应数据，求算结构系统等效动力学模型中各动力学参数等效值的待定参数法；（2）为了提高识别精度，对动力学参数进行优化的方法．然后通过试验，验证了这些方法的可行性．

| Abstract: | A technique is presented for dynamic modelling of a mechanical structure. It is required to establish an equivalent lumped parameter dynamical model for a given structure. Then, by means of undermined parameter methodology, the dynamic parameters of the mechanical structure are calculated from measured response data. In order to raise the accuracy of identified parameters, an optimization procedure is used.This technique has been applied to modelling of a drill Z512-2, and good result was obtained. |
