Abstract

Abstract:

Once a complicated machine such as a reciprocating compressor or a combustion engine malfunctions, it is most important to locate the fault in it.This paper introduces two patterns to judge the fault position, which are based on measuring vibrational accelerations.With the real examples on a reciprocating compressor and a combustion engine, the two patterns proposed were verified to be feasible to some extent, and the multiple feature based pattern was more effective than the one feature based pattern.

Key words: fault position, diagnosis, a ccelerat ion
