When a stiffener is set along a curve the following sub-syntax should be used.
|
<along_curve>::= |
CURVE = <curve_name>, |
|
[,M1 = <dist>] |
|
|
,<end_1> |
|
|
/<end_2> |
|
|
<end_<i>>::= |
[CON = <con_code>, [<stiff_ref]] |
|
[,<line<i>>] |
CURVE specifies the name of the curve along which the stiffener should be set. This curve may exist in the databank but is normally supposed to be created in the same input scheme.
The curve may be parallel displaced as specified by M1 (>0 to the right, <0 to the left). If M1 is not given the stiffener will follow the curve itself.
The stiffener may end in one of the following ways:
-
By the intersection with a given line.
-
By connection to a given stiffener in the same panel.
-
By connection to a given hole in the same panel.
-
By connection to a given seam in the same panel.
-
If no line and no stiffener are given the stiffener will end at the intersection between the curve and the outer contour of the panel, provided an appropriate connection code is given.
-
If none of this is fulfilled the stiffener will end at the end point of the curve, that means, when no restricting line or stiffener is defined, when no appropriate connection code is defined or when the curve has no intersection with the outer contour.
Examples:
1.
In the image the solid line is the curve, the dashed line the stiffener.
STI, ... , CUR='ABC',... /CON=15....;
2.
.
The stiffener follows the curve and is connected against two stiffeners.
STI, ... , CUR='DEF'
S5, CON=14, ... /
S6, CON=14, ... ;
