In　this　paper,　the　traditional　parameter　analysis　method　is　used　to　analyze　several　typical　acoustic　emission　signal　of　rolling　bearing　failure.　The　trends　of　several　commonly　used　AE　parameters　of　different　types　of　rolling　bearing　failure　are　summarized　and　the　sensitivity　of　different　parameters　to　various　faults　is　also　analyzed.　In　the　end,　the　diagnostic　effect　of　the　AE　parameters　for　the　rolling　bearing　fault　is　given　through　comparing　the　results　of　statistical　parameters.
