Vessel With Endcaps

This help topic is not fully complete. An example can be found by following the link.

Different end-caps can be specified for each end of the mandrel from the pull down list box, the end caps have parameters R1, R2 & R3. The dialog and End-cap types are shown below

For the conical end cap (not shown above) the R2 parameter is the axial length to the apex of the cone. The clearance parameters are explained in the following diagram. Please note that having C2 > half the with of the payout head is advisable to avoid collision with the end-cap.

The user also needs to specify the fibre band-width (W) and Winding angle (A).

For unequal end openings the non-geodesic box can be ticked and then the openings at each end can be specified. Please note that these are for the centre line of the band so an end opening radius 0.5*W larger than required should be used. There are some known issues/problems with the non-geodesic winding on this option.

The zero Wind tick box is a special option for zero degree  winding through pins at the cylinders ends and is described elsewhere.
