| 摘 要： | 分别按集中参数法及有限元法建立了塔式起重机结构系统的动力学模型．按集中参数法建立的少自由度模型包括四自由系统、三自由度系统、二自由度系统及单自由度系统，时二自由度系统及单自由度系统的结构固有频率给出了简化计算公式。通过实例验算证明，少自由度系统或简化计算公式的计算精度可以满足工程设计的要求。

| Abstract: | This paper presents dynamic structure models using Lumped Parameter Method(LPM) and Finite Element Method (FEM) respectively. The proposed low-Degree of Freedom (DOF) LPM models include four DOF system, three DOF system, two DOF system and single DOF system. The calculating methods of natural frequency for two DOF and single DOF system with simplified formula are given. A numerical example is used for illustrating these proposed models. |
