az31 magnesium alloy sheets were rolled by applying a circumferential velocity ratio of 1.125 between the upper and lower rolls in different diameter rolling.
采用上下轧辊速比1.125的异径异步轧制方法对az31镁合金板材进行轧制。
developed the simulative model of the locomotive traction system considering the characteristics of adhesion, denoised denoised the circumferential velocity of the wheel using wavelet analysis.
