■ Calculation of an existing screw connection: The user selects an existing
screw connection to be calculated. All geometric and standard-related data
is taken from the screw connection and cannot be edited.
In this exercise, you use the stand-alone Screw Calculation. With the
standalone calculation, you can calculate a screw connection without any
prerequisites. You can specify the screw connection in detail (material,
geometry, load, settlement and tightening properties). In this exercise, you
are provided with the drawing of a screw calculation. Some values are selected
from tables, some are entered manually, and some are taken directly from the
drawing.
To open the initial drawing
1 Open the file tut_screw.dwg in the tutorials folder at:
■ Windows Vista
™
: C:\Users\Public\Public Documents\Autodesk\ACADM
2009\Acadm\Tutorial
■ Windows
®
XP: C:\Documents and Settings\All Users\Shared
Documents\Autodesk\ACADM 2009\Acadm\Tutorial
The drawing contains the representation of a screw connection.
2 Save your file under a different name or to a different directory to preserve
the original tutorial file.
Problem for this exercise
■ Two hollow shafts made of Cq 45 with forged coupling flanges are to be
connected by 13 hex-head bolts ISO 4017 M12 x 45 - 10.9, which are
arranged at a pitch diameter of 130 mm.
■ The through holes are according to ISO 273 close.
