Vibrational Damping Analysis of Composite Material Based on Python-ABAQUS

摘要

:基于Mindlin一阶剪切变形理论,结合纤维增强树脂基复合材料结构的模态应变能分析方法,采用Python脚本语言二次开发ABAQUS的前处理模块和后处理模块,实现了板、空心轴、球壳的参数化建模以及结果自动后处理,获得了模型各阶固有频率下的应变能和阻尼损耗因子.该脚本程序简化了建模与计算过程,有着良好的人机交互界面,并可以实现参数优化,提高了计算效率.%The strain energy and damping loss factor of fiber reinforced composite sturctures,such as panels,hollow shafts and spherical shells,under each frequency,was achieved based on Mindlin first order shear deformation theory and strain energy method (SEM).A plug-in was programed to auo-generate these models and postprocess the results automatically,which simplifed the process of model buliding and simulation.In general,it can offer a good operation interface and improve the compute efficiency,which may be helpful for the structural optimazation analyzing.
