5(1/4)温盘机头盘系统的结构动态特性研究

Dynamic Behaviour Analysis of Structures of Head-disk System in 5(1/4) Winchest Disk

本文将拓扑图的多口网络点边关联矩阵引入固定界面模态综合技术,使模态综合过程规范化,子结构划分更加方便,提高了系统综合能力.该方法可用于子结构串联、并联和混联构成的任意系统模型.用所编制的动力程序分析了5(1/4)温盘机的头盘组件(HDA系统)的动态特性,还采用动态全息照相技术验证了理论分析结果.

In this paper,the multi-port-network vertex-edge incident matrix of topology graph is used in constraint modal synthesis technique. By this way, we can regularize the course of modal transformation,divide substructures more easily,and improve the synthetic ability for the system.This method is available to arbitrary system modal that is made up of the substructures on series,parallel,or series-parallel.We have designed the general synthetic dynamic analysis program (GSDAP) and have been successful in analyzing the dynamic characteristic of the head disk assembly (HDA) in 5(1/4) Winchest disk.
