Abstract

In order to improve the efficiency and accuracy of gear fault identification under variable speed conditions

an intelligent fault identification method of variable speed gear

namely INGO-CSA-LSTMN

was proposed based on improved northern goshawk optimization (INGO) algorithm to optimize convolutional self-attention long short-term memory network (CSA-LSTMN). In response to the problems that the traditional northern goshawk optimization algorithm taking too long training time and being easy to fall into local optimization

an INGO algorithm was proposed by introducing sinusoidal pulse modulated chaotic map and random Levy flight strategy

and it was applied to optimize the key parameters of the CSA-LSTMN model to improve the stability and training efficiency of the model. The validation through test functions demonstrates that the INGO algorithm has a faster convergence speed and can find the optimal solution more accurately. The analysis of gear datasets from two different experimental rigs reveals that compared to other commonly used network models

the INGO-CSA-LSTMN model has higher recognition accuracy for gear faults under different operating conditions

with the accuracy rates exceeding 99.9%.
