摘要
利用ＯＤＳ（ＯｐｅｒａｔｉｏｎａｌＤｅｆｌｅｃｔｉｏｎＳｈａｐｅｓ）法分析了织机机架结构在织机运转状态下的动态特性，并同机架结构的模态分析相结合，找出了机架的薄弱环节之所在，为机架结构的改进提供了可靠的依据。文章指出：ＯＤＳ分析与模态分析两种方法相结合，将从结构振动的内因与外因两个方面认识结构的动态特性，为结构改进提供可靠的依据。
The ODS(Operational Deflection Shapes) method is used to recognize dynamic characteristic of structure under operating condition. By comparing the ODS analysis with modal analysis of loom frame, the structural weakness of loom frame will be found out. This paper points out, by combining ODS with modal analysis method, that dynamic characteristic of the structure can be recognized through internal and external factors of the structure. The method used in this paper provides a reliable basis to structure modification.
