摘 要: | 振动是工程结构的一种常见现象,模态分析就是确定结构的振动特性,它也是其它动力学分析的基础。利用大型通用有限元分析软件ANSYS对广泛应用于工程中的某型塔式起重机的振动频率和振型进行分析计算,为研究该型塔式起重机其它的动力响应提供依据。

Abstract: | Vibration is the common phenomenon in engineering structures. We use modal analysis to determine the vibration characteristics of a structure. It also can be a base for another dynamic analysis. The natural frequencies and mode shapes of a tower crane, which is used in engineering widely, is calculated by means of computer program-ANSYS and provides a preparation for another dynamic response analysis. |
