| Abstract: | In order to obtain the optimal range of surface roughness processing parameters for wind turbine bearing materials by the ultrasonic rolling extrusion within a given range, for wind turbine bearing materials sample made of 42 CrMo steel, the ultrasonic rolling extrusion the surface roughness test was conducted, and the surface roughness exponential function prediction model was constructed based on the test result. Then, the influences of the processing parameters on the surface roughness and the sensitivity were analyzed, the stable and non-stable regions of processing parameters were determined, and the best ranges of surface roughness processing parameters for ultrasonic rolling extrusion 42 CrMo steel were selected. The results show that the influence degree of the processing parameters on the surface roughness is static pressure Fs, rotate speed n of workpiece, feeding speed f and amplitude A, and the optimal range of n, f, A and Fs is 500-600 r·min-1, 35-45 mm·min-1, 15-20 μm and 400-500 N, respectively. |
