Abstract

Aiming at the rub-impact fault between the rotor and stator in rotating machinery, the development about the rub-impact experiments is summarized in this paper. The rub-impact devices for single point rub-impact, local rub-impact and full annular rub-impact are introduced and typical experiment phenomena caused by these three types of rub-impact are analyzed. The main rub-impact form in practice projects is local rub-impact. According to different research objects, researches on local rub-impact experiments are divided into four types: (1) local rub-impact of the simple rotor system, (2) local rub-impact of the complicated rotor system, (3) local rub-impact of rotating blade-casing, (4) local rub-impact of the practical unit. Finally, the typical fault features of the three types of rub-impact are compared and the new research directions about the rub-impact experiment are suggested.
