| 摘 要： | 通过计算机模拟,采用跟踪复合轧辊表面轮廓线坐标的方法(坐标跟踪法),计算复合轧辊在不同时刻的形状和尺寸.并分析各种喷射铸造工艺参数对复合轧辊形状的影响规律,模拟结果表明,辊芯平移速度和辊芯半径的变化对复合轧辊的沉积层厚度影响较大,而辊芯旋转速度和喷射距离的单独变化对轧辊沉积厚度影响很小.

| Abstract: | Through numerical simulation,a shape mathematic model of clad rolls using a coordinate tracing strategy was established to calculate the shape and dimensions of the clad rolls at various spray times and studied the influences of processing parameters.The research results show the shapes of the clad rolls are influenced dramatically by the traveling speed and diameter of the mandrel.However,the influence of rotating speed of the substrate and spray distance on the shape of the clad rolls is rather small. |
