Abstract:The damage signal of high speed composite flywheels was collected by acousticemission method.The relation between damage type and damage signal was discovered by supplementary detection methods such as stereology microscopyl optical microscopy and coloring penetrating testing.The damage type of fly wheels was distinguished by the trained artificial neural network Research on the failure cause of high speed composite flywheels showed that the failure was caused by the through circular crack.
