Harmonic BEM mode 1. Tools-modal type definition 2. Import file.rst Cavity meshing mode 3. Insert-Pre/acoustic mesher-shin mesher,提取结构边界网格 Harmonic BEM mode 4. 定义或导入field point mesh 5. 设置mesh type,skin mesher设置为acoustic mesh 6. Acoustic mesh preprocessing 7. 定义 Fluid materials 8. 定义Acoustic fluid properties 9. 有限元结构表面单元组定义,mesh group-auto update group,形成surface group set 10. Data transfer anslysis 选择file.rst(或mode set.1) source:surface group set target:acoustic mesh 11. 定义Boundary condition/sources displacement, vector(对于ansys模态分析、谐响应分析的结果文件.rst) face: acoustic mesh data source: data transfer solution set.1 12. 求解Acoustic response case frequency form BC或者自定义频率范围 13. 求解Acoustic field response case 注:1、第9步可以不做,直接做第10步,其中source选择导入的结构有限元网格即可。 2、Ansys Workbench分析结果可以是模态分析结果,也可以是谐响应分析结果。 转自:http://blog.sina.com.cn/s/blog_6c422eb70102wu3b.html |
