SI Unit Example |
ID |
Identification number referenced by MASSSET
Subcase Information Entry. No default (Integer > 0)
|
|
SA |
The overall scale factor for the linear combination. Default =
0.0 (Real)
|
|
Si |
The scale factor for the linear combination. Default = 0.0
(Real)
|
|

Comments
- This entry is referenced by the MASSSET Subcase
Information Entry.
- Fixed reference frame method is adopted for 3D rotor dynamic
analysis.
- The mass of a section is calculated as:(1)
Where,
-
- Mass of the linear combination of mass cases.
-
- Overall scale factor of the linear combination.
-
- Scale factor of the i'th mass section.
-
- Mass of the i'th mass section identified by the
IDi field. It is the mass of the mass
section defined on the corresponding
BEGIN,MASSID
entry.
-
- ID of the MASSID section; i = 0 is the base
mass case.
- IDs for mass sections defined on the MASSSET Bulk
Data Entry should be unique.
