Definition of the Bevels in the Modelling

In plane panel generation the user may define beveling in the following contexts.
-
Along seams in the panel (keywords BEV, RBEV, LBEV in the SEAM statement).
-
Along the outer contour of the panel (WELD statement).
-
At the ends of profiles (stiffeners, flanges) (keyword BEV) and along the trace of stiffeners (keyword TBE).
-
Along the edges of brackets (keyword BEV).
This is always done by reference to customer defined bevel codes. The format of the user bevel definition may be:
<bevel>::= [-]<bevel_code>[<variant><e-measure>]
|
<bevel_code> |
Number or name of a customer defined instance of one of the basic bevel types, see below. If a code is given then it must be a positive integer < 1000. If a name is given it must have been defined in the bevel object. |
|
The bevel code must be a positive integer < 1000. |
|
|
<variant> |
One of the variants as specified above (in the range 1-4, 9 - normally relevant only for bevel types for butt welding). |
|
<e-measure> |
The thickness of the plate on the other side of the joint (in mm). Always two digits (if <10 then a leading 0 should be added). |
The minus sign indicates that the bevel should be seen from the opposite side of the panel or bracket (that means, in the direction of the negative w-axis of its local coordinate system). For stiffeners the bevel code is positive if its positive side is seen from the mould line side (web) or top (flange), negative otherwise.
If bevel names are used and <variant> and <e-measure> should be given then the following keywords are available:
BVA to give the bevel variant.
BEM for e-measure.
BVA and BEM is used together with BEV.
TBV and TME is the bevel variant and e-measure to be given together with TBE (trace bevel).
|
Examples: |
|---|
|
BEV = -101 |
|
BEV = 201107 |
|
BEV = 305120 |
As an alternative the bevel can be given as a name. In that case; variant, e-measure and side are given with separate keyword.
|
Examples: |
|---|
|
BEV = V50 |
|
BEV = V50, BVA=1, BEM=7 |
|
BEV = K15, BVA=1, BEM=20 |
Remarks:
-
Thus the user defined bevel must be either a 3-digit or a 6-digit number (actually, decimals would be accepted in the e-measure). However, bevel codes < 100 are accepted.
-
Along seams in panels the user normally specifies only the bevel code. From customer defined rules the system will automatically evaluate the variant and the e-measure from the relative positions of the involved plates.
However, if these parameters are defined directly by the user they will always override the values that would otherwise have been derived based on the bevel definition file. -
In other cases (bevel along outer contours, in brackets and in profiles) the variant and the e-measure must be user supplied. If variant 0 is wanted, of course only the bevel code need be given.
(An exception is if the keyword EQUAL has been used in the WELD statement. If so, the variant will be evaluated automatically.)
