介绍建立管道结构的有限元模型,用ANSYS程序对它进行分析,得出管道结构固有频率和振型,从而判断管道是否与振动主频率产生共振,并为管道的动态设计和减震提供依据。
The finite element model of the pipeline structure is introduced. The ANSYS program is used to analyze the natural frequency and shape of the pipeline structure to determine whether the pipeline resonates with the main frequency of vibration and provide the basis for the dynamic design and damping of the pipeline.
