摘要：

By simulation experiments, the relation between the starting friction torque of a blade bearing and the overturning moment is explored in order to disclose the nonlinear evolution characteristics of the sample mean and variation coefficient of the starting friction torque. Via the variation analysis of the test data, the result indicates that with the rise of the overturning moment, the sample mean is nonlinearly increased and the sample variation coefficient is nonlinearly decreased in view of the overall situation, at which there is a sensitive spot where the sample variation coefficient makes larger abnormally. This is a new discovery. Perhaps it can lay the foundation for analyzing the starting friction torque measurement system and for designing the blade bearing system.
