The effective method of fault diagnosis of rolling bearing is studied,and current main methods have neutral network,expert system method,fuzzy mathematics,and other methods,but when these methods are used to have fault diagnosis of rolling bearing,but fault diagnosis data obtained exist deficiency of non-precision and non-complete which will get mistake fault results.And simulation results show that fault diagnosis precision obtained by using this improved method achieve 100%,and these results show that this method had higher fault diagnosis precision,which have every important applicable value for having fault diagnosis for rolling bearing.
