Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0036] The embodiment adopts a certain locomotive bearing test bench, such as figure 1 As shown, the test bench is composed of hydraulic motor, driving wheel, bearing and locomotive wheel pair. The hydraulic motor drives the driving wheel to move and then drives the outer ring of the bearing to move. The inner ring of the bearing is fixed on the axle of the locomotive wheel set. The acceleration sensor is fixed on the At one end of the bearing, the vibration signal of the bearing is measured.
[0037] The wheel bearing in the test bench is diagnosed by using the maximum correlation kurtosis deconvolution method without period, and the experimental data are analyzed and compared with the traditional maximum correlation kurtosis deconvolution method.
[0038] Such as figure 2 As shown, a cycle-free maximum correlation kurtosis deconvolution method in...
