【摘要】 通过在相同辊子垂直度缺陷下不同辊子弯曲变形缺陷的对比分析及在相同辊子弯曲变形缺陷下不同辊子垂直度缺陷的对比分析，研究相应的划痕特征变化趋势。研究方法为通过SolidWorks分别建立模型，再通过Adams进行运动仿真得到划痕轨迹坐标，最后利用Matlab得到划痕曲线，分析划痕曲线特征的变化趋势。结果表明：随着辊子垂直度缺陷的增大，划痕曲线逐渐由竖直变得扁平，且划痕两端弯曲程度逐渐增大；随着辊子弯曲变形缺陷的增大，划痕曲线逐渐由扁平变得竖直，且划痕两端弯曲程度逐渐减小。更多还原

【Abstract】 Through the comparative analysis of different roller bending deformation defects under the same roller verticality defects and the comparative analysis of different roller verticality defects under the same roller bending deformation defects, the change trend of corresponding scratch characteristics is studied. The research method is to establish models respectively through SolidWorks, and then obtain the scratch track coordinates through Adams motion simulation. Finally, the scratch curve is obtained by MATLAB, and the change trend of the characteristics of the scratch curve is analyzed. The results show that with the increase of the verticality defect of the roller, the scratch curve gradually becomes flat from vertical, and the bending degree of both ends of the scratch gradually increases. With the increase of roll bending deformation defects,the scratch curve gradually becomes vertical from flat, and the bending degree at both ends of the scratch gradually decreases.更多还原
