Fault Diagnosis for Rolling Bearings Based on Ant Colony Algorithm-Neural Networks

In order to improve the accuracy of rolling bearing fault diagnosis,a method of ant colony algorithm combined with neural network model is applied.According to the mechanism of bearing failure,the BP neural network diagnostic model is established.Taking the error as objective function,the weight of BP neural network is optimized by using multiple generation computation of ant colony,and then the fault diagnosis is accomplished via the optimized BP neural network.The simulation results show that the method has high accuracy of fault diagnosis,with a strong practical.
