摘要： 利用ANSYS软件，采用模态应变能法，通过APDL语言编程，近似计算粘弹性复合管道结构的动力问题，应用MTLAB软件对ANSYS计算结果的比较，得出一些关于不同开孔方式对管道阻尼结构减振效果的对比结果，为实际工程类似管道结构设计提供一些借鉴。

Abstract: The structural dynamic problems of viscoelastic composite pipelines were calculated by means of ANSYS software based on the modal strain energy method, and the APDL code was used for programming. The results were compared with those from the Matlab code. Some results of the effect of different perforating patterns on noise reduction of the pipeline’s damping structure were provided. This work may provide a reference for similar engineering projects.

Key words: vibration and wave , pipeline , viscoelastic damping structure , modal strain energy method
