Problems solved by technology

Second, the data generated using GAN has no classification labels in the instances and cannot be directly used in classifiers
Although using instances in a class as input to a GAN can label the generated data, it cannot guarantee the efficiency of learning assignments due to the inadequacy of each class
Third, in trad

Abstract

The invention provides a gear reliability analysis system based on boundary constraint generation antagonism network, which is characterized by comprising an original data sampling module, a generation antagonism network module, a mean covariance marking module and a classifier, wherein, the original data sampling module is used for acquiring the original parameters of the gear and normalizing theoriginal parameters; the generating countermeasure network module comprises a generator and a discriminator, and a boundary constraint module is arranged between the generator and the discriminator.A mean covariance mar module is used for mar that final generated data of the generated antagonistic network module; classifier: selecting part of the original parameters and part of the generated data after tagging as the final composite data set for security classification. The effect is that more instance data can be generated and effectively marked, and the data generated by constrained GAN has better reliability classification ability.

Description

technical field [0001] The invention relates to mechanical equipment reliability analysis technology, in particular to a gear reliability analysis system based on boundary constraint generation confrontation network. Background technique [0002] The transmission gear provides the main transmission power for the vehicle and regulates the speed and direction of the vehicle's motion. Due to the complexity of the repair process of the gear, its maintenance and downtime costs are high. More than 60% of transmission failures are caused by gears, and gear reliability is a key indicator for evaluating gear safety. Therefore, accurate classification of the safety and reliability of gear parameters is the key to ensure the transmission operation. [0003] However, the lack of gear data with full-scale parameters leads to a high misclassification rate. In practice, gear parameters are obtained through four steps. First, initialize the gear parameters with empirical values. Second...
