Hello!

I have a 100liter pressure vessel that is made up of composites. I wanted to know if we can simulate the filament winding process in acp. It consist of hoop winding and helix winding. How can i simulate this in ansys acp? 

I created few plies in ansys acp but that doesn't represent the actual winding of composite filament. I was able to make layers something similar to below image, in which a layer is covering entire surface area of the vessel.

But i wanted it to be winded, How can we define layups that are similar to below image. How can i simulate Composite winding in ansys acp.

 

Your help would be appreciated.

Thanks!

Hello,

Ansys Composite PrepPost (ACP) was developed mainly to pre and post process layered composites. But, if you assume that one wrap of filament is one layer, then you can use ACP to model a filament wound pressure vessel. So, for each wrap, you need to have one layer defined.

To specify the fiber angle and layer thickness, you have 2 options:

1. Use a Python script in ACP to calculate the fiber angle and layer thickness based on location on the cylinder and create a lookup table in ACP. Or, if you have the angle, thickness data defined vs location (x, y, z coordinates)  for the cylinder in Excel, txt, or csv format,  you could use a Python script to read the angle, thickness vs X, Y, Z from .csv or .txt files and create a lookup table in ACP. The lookup table will be used to map the angle and thickness of each layer of filament winding. The thickness is defined in the "Thickness" tab of the modeling ply and the fiber angles are defined in the "Draping" tab of the modeling ply.
2. Transfer the composite layup using a HDF5 file. Filament Winding tools such as CADWIND and CADFIL support the HDF5 composite format.

 

You will find an on-demand webinar on pressure vessel with Ansys and CADWIND here:

Let me know how it goes.

Hello,

Did you create lookup table of pressure vessel ? Please help me to create lookup table.
