The analysis of rotating equipment difficulties is
currently accomplished by a specialist in rotating
equipment examining the signs and symptoms of the
equipment, applying his expert judgement, and determining
the cause of the machine's difficulty. This thesis covers
the development of an off-line expert system that can be
used to emulate the expert's ability to interpret the
signs and symptoms of the machine, including suggestions
of possible further actions to take for repairing the
problem or refining the proof for the proposed cause the
difficulty. An editor has also been built which will
allow an expert to keep the information used by the system
current with the state of the art for rotating machinery
diagnostics. This thesis documents the development of the PC—based Turbo Prolog expert shell and external knowledge-base editor. The use of the system editor is illustrated
by loading current diagnostic table information into a knowledge base. Then the expert program's operation is illustrated by applying the editor-formed database in a
typical session. The expert shell and knowledge base can
operate as a stand—alone unit for field application.
Resident experts in machinery diagnostics can build and
update databases for distribution to users in the company
to assure full uniform utilization of the current and most
