摘要
振动是工程结构的常见现象,模态分析就是确定结构的振动特性,它也是其他动力学分析的基础。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他的动力响应提供了准备。
Vibration is common in engineering structure. Modeanalysis can determine structure vibration characteristics and is the foundation of other mechanics analysis. This paper applies the general powerful finite element analysis software ANSYS to analyze and calculate vibration frequency and vibration patterns of a widely used type of tower crane, making preparations for the following dynamics response analysis of this type of crane.
