弧半径较小、矫直段较长的连铸机采用康卡斯特方程描述理想矫直曲线会产生较大的计算误差,在矫直曲线起始点会发生曲率的突变。编写了基于泰勒级数方程的计算理想矫直曲线的可视化程序。在实践中,运用该程序进行计算不但可以控制误差,而且可以方便地得到理想矫直曲线任一点的坐标值和法线斜率。 The small arc radius and long straightening section of the continuous casting machine using Comcast equation to describe the ideal straightening curve will produce a large calculation error, curvature curve at the beginning of the curvature changes will occur. A program to calculate the ideal straightening curve based on Taylor series equations was written. In practice, using this program to calculate can not only control the error, but also conveniently obtain the coordinate value and the normal slope at any point of the ideal straightening curve.
