大型造纸机振动的三维有限元分析

3-D Finite Element Analysis on Giant Paper Machine Vibration

以大型造纸机为研究对象,采用土-结构动力相互作用分析的子结构方法,建立包括地基、基础以及机器的三维有限元模型,对机器基础系统进行动力分析。介绍并讨论动力分析的基本理论、模型建立以及结果处理方面的若干问题。

The investigation object of this paper is giant paper machines. Using the sub-structure method, which is used in the analysis of dynamic soil-structure interaction, the three dimensional finite element model including the subgrade, the foundation and the machine frame is established for the dynamic analysis of the system. Some issues concerning the fundamental theory of dynamic analysis, the modeling and the result processing are presented and discussed.
