FINTTE ELEMENT METHODS IN VIBRATION ANALYSIS OF MULTI-STORIED WEAVING BUILDINGS

本文用有限元法、子空间叠代法、振型叠加法完成楼层的竖向振动、厂房的水平振动的分析计算。振动计算先计算单机动力作用下结构的动位移,再用《多层织造厂房结构动力设计规范》中动位移合成方法计算多台布机作用下的动位移。

Using finite element methods, sub-space iterating methods and vibration mode summation methods, this article successfully analysed and calculated the vertical vibrations of the stories of the textile building and the horizontal vibrations of the factory construction. In the vibration calculation, the dynamic displacement caused by each machine was first worked out, and then the dynamic displacements caused by all relevant textile ma- chines were composed according to Standards on Structural Dynamic Design of Multi-Storied Weaving Buildings.
