Hi Everyone!
ROMAC bearing code is one of popular bearing codes used in Rotordynamic field. It is developed by ROMAC Lab. at the University of Virginia. We have already had a partnership with ROMAC and been working closely with them. Since we have a new rotordynamic load, ROTDYNF, in Abaqus 6.12, you can perform rotordyamic analyses easily with the bearing property information given by ROMAC bearing code.
The plug-in is useful to import the bearing properties from the ROMAC bearing code THPAD, THBRG, and MAXBRG and write those in Abaqus input format. You can also fill out the bearing properties manually and write them in Abaqus input format using this plug-in.
The Abaqus input file .inc (which contains the properties of the connector element of the bearing with a given bearing name), is created using the plug-in. You can use the created properties in the proper connector element in your own model.
Three separate plug-ins allow for three different approaches to entering the bearing properties.
- Calculate Coefficients
- Manual Input
- Read from File
The Calculate Coefficients plug-in directly runs the ROMAC bearing software (THPAD or THBRG) and writes the bearing properties in an Abaqus input file. The output file name is set as .inc using the bearing name which is assigned in the plug-in by default, after importing the bearing results. You must have the ROMAC bearing software (THPAD or THBRG).
The Manual Input plug-in allows you to enter the bearing properties manually and write them to an Abaqus input file.
The Read from File plug-in reads the ROMAC bearing output file and writes the bearing properties in an Abaqus input file.
Notes
- By default, ROMAC uses English units. The plug-in can convert it to SI units.
- For uncoupled property, there is no version limitation. But for coupled property, only Abaqus 6.12 and later is available.
- The detailed information can be found in attached pdf.
