摘要
基于缓和曲线平行线弧长公式及其性质，给出了缓和曲线平行线以其自身弧长为变量的参数方程。提出了计算直线与缓和曲线平行线交点坐标的严密方法。通过实例计算，证明该方法具有解算原理简单、便于计算机编程的特点。
Based on the arc length formulae of the parallel to the easement curve and its property, this paper gives the parameter equations of the parallel to the easement curve taking the arc length itself as variable. It presents the rigorous method to calculate the intersecting point coordinate of the straight line with the parallel to the easement curve. By case history calculation, it proves that this method is characterized by its simplicity of solution principle and covenience in computer programming.
