Fault Diagnosis of Gearbox based on Multi-fractal and PSO-SVM

Fault Diagnosis of Gearbox based on Multi-fractal and PSO-SVM

Aiming at the non-stationary and nonlinear of gearbox vibration signals,a fault diagnosis method based on the multi-fractal and particle swarm optimization support vector machine（PSO-SVM）is put forward.Firstly,the fractal filter with short-time fractal dimension as fuzzy control parameters is used t...
