摘要
process for introducing a voluntary du00e9saccordage aubagu00e9e of wheelturbomachine determined so as to reduce the vibration level of thewheelin the forced response, characterized by the fact that it is.functionthe operating conditions of the wheel on the inside of the turbomachine.aoptimum value of standard deviation of du00e9saccordage relative to the maximum responsein the vibration amplitude on the wheel will have on the wheel atlessin part, the blades of different frequencies, so that thefrequency distribution of the whole blade has a standard deviationless than the value of the value of du00e9saccordage du00e9saccordage.sincestatistically determined.
