First, making a simple analysis about types and failure forms of drums then build drums model by dimension parameters which were detected. And add appropriate constrains on the driving drums to detect and map the charts of stress and displacement. Secondly, using Solidworks builds drums model because it is little complex in ANSYS. Finally, f
