Abstract: In order to diagnose whether or not tiny air leak from flywheel housing before its delivery, based on linear regression analysis of correlation of flywheel rotating speed and work time, a construction method of flywheel sealing leak prediction model is developed. For the purpose of insuring the accuracy of model and practicability in engineering, the variance, statistical test and correlation of the model are analyzed. This construction method is suitable for all kinds of flywheels or other performance parameters to construct the corresponding prediction models, and a high reliability of flywheel sealing can be insured before they are delivered to customers.
