ARMD – Main

1.0 INTRODUCTION AND HISTORICAL BRIEF ARMD (Advanced Rotating Machinery Dynamics) is a new generation software package developed by RBTS to bring you the most advanced and complete rotor/bearing analysis capabilities for evaluating practically any bearing, rotor/bearing system, or mechanical drive train. ARMD is developed for performing:

• Rotor Dynamics • Torsional Vibration • Fluid-film Bearings • Rolling-element Bearings • Lubricant Temperature-dependent Properties

ARMD is an integrated analysis package that incorporates state-of-the-art numerical and modeling features giving the ability to evaluate the physical system accurately and efficiently. ARMD is user-friendly with options and features that include:

• Context-sensitive help • Menu and windowing environment • Inter-module communication and data exchange • Graphical and text capabilities • Data range checking • Advanced file management system • Advanced mouse support features

ARMD was developed in-house by RBTS' principals who, prior to 1986, were employed at The Franklin Institute Research Laboratory (FIRL). FIRL was an internationally known scientific and engineering organization dating back to 1824. Since 1950, FIRL was a leader in the field of tribology and rotating machinery dynamics. RBTS' principals since the early 50's were, and still are, involved in the area of tribology and machinery dynamics. They have provided industry with engineering technical support and software for the design, development, fabrication, and application of fluid film/rolling element bearings and seals. RBTS has been at the forefront in the development of advanced software for the evaluation of bearings, bearing systems, and vibration associated with rotating machinery and drive trains.

5.0 OPERATION

5.1 General Operation When the ARMD package is installed, the installation, by default, will install the user interface programs, solvers, help files, manuals, DLL’s and system files in the Program Files folder under the folder name “ARMDW57demo”. All other files including Templates, Samples, Lubricant & Material Properties, User files, etc. will be installed in

e shared documents folders under the folder name “ARMD57demo”. As an example, for Windows 2000 & XP

th

operating systems the user interface programs, solvers, help files, manuals, DLL’s and system files will be installed in the default folder “C:\Program Files\ARMDW57demo”, and all other files including Templates, Samples, Lubricant & Material Properties, User files, etc. will be installed in the shared documents folder “C:\Documents and Settings\All Users\Documents\ARMD57demo”. For Windows VISTA/7 operating system, user interface programs, solvers, help files, manuals, DLL’s and system files will be installed in the default folder “C:\Program Files\ARMDW57demo”, while all other files will be installed in the shared documents folder “C:\Users\Public\Documents\ARMD57demo”. Once the software package has been installed and the computer system has been setup and as described in Section 5, you can run the ARMD software from the Windows Start menu. The first screen of ARMD will be displayed as shown below.

5-1

ARMD – Main

At this point, you are at the top level of the software package and from this level you can activate any of the preprocessor modules for bearings, bearing systems, rotor dynamics, torsional vibration, or lubricant properties calculation. Once a preprocessor module has been selected, from the front end, the program will activate the selected preprocessor. Details for each of the preprocessors and their operation is described in the corresponding sections of this manual. The ARMD package is fully user-friendly with context-sensitive help. Function keys commonly used include the following (multiple key combinations are in the form [key1+key2]): [Tab] Moving to next field. [Shift+Tab] Moving to previous field. [Home], [End], [Page Up], [Page Down], and Arrow Keys For moving around the screen and

data fields.

[F1] On-line help.

[F2] Display list of choices for field (if available).

[Ctrl+P] Print text or graphics screen to printer. OK button Save edits and close form. [Esc]/Cancel button Cancel/abort. ARMD’s built in capabilities permits the usage of the right mouse button that incorporates all function key operations and more. This capability eliminates the need of the above function keys and gives the user built-in edit capabilities by simply pressing a button.

[F7] Execute post processing programs in the bearing routines.

ARMD – Main

Briefly, a typical session with ARMD may be as follows; 1- Select a module from the front end (for example, TORSION).

2- Place a problem in memory. To use an existing file, use the File>Open command and select an existing one. To create a new file, use the File>New command. 3- Edit the contents of the input file. If you need help at any time, press the F1 key

(Help button) to display context-sensitive help or go to the help menu. 4- Save the file under a filename. Variations of an input file can be stored using the File>Save As command. 5- If you want to examine the input file, you can look at it on the screen with the View>Input File command or print it using the File>Print command. 6- Once the input file is setup with parameters and saved, execute the appropriate processor/solver from the Run menu. 7- After the processor executes, examine the text and graphic output files generated by the processor using the Text Output (RBTSTYPE) and Graphics output (RBTSGRAF) utilities from the View menu. - When you are finished with this preprocessor, run the

command File>Exit to return to the top-level of ARMD menu.

- From the ARMD front end, close the window to quit ARMD.

Graphics utility permits user defined graph settings, scaling, and many other options.

Graphics screens can be copied to other applications such as word processors and presentation utilities for preparation and presentation of technical reports.

Torsional natural frequencies can be dynamically excited by rotational speed or other sources of excitation such as the pulsating torques in synchronous motor during start-up. TORSION predicts dynamic amplification and performs fatigue analysis for determining system acceptability for its intended application.
