本程序用719机算法语言编制。供一般情况(无控制点、两端采用等长缓和曲线)下整正既有线单曲线之用。其特点是利用差分法区分圆曲线和缓和曲线并直接求算最优圆曲线半径和相应的缓和曲线长度,与人工给定若干组合方案,由机器对每个方案计算后再从中选优的方法相比,具有节省机器时间和不致遗■最优方案的显著优越性。文中简明扼要地阐述了本程序所用算法的基本原理和步骤,说明了程序的功能,以及程序中所用过程和标识符的意义,并附有计算机■印的源程序和实例的计算结果。本程序可供生产实践应用,也可作为《选线设计》课的补充参考资料。
This program is compiled with 719 machine language algorithm. For the general case (no control points, both ends of the curve with the same length of ease) to correct the existing single line curve purposes. It is characterized by the use of differential method to distinguish between the circular curve and the easing curve and directly calculate the radius of the optimal circular curve and the corresponding length of the easing curve, and manually given a number of combinations of programs by the machine after each program and then select the best method Compared with the machine has saved time and not leave the best solution ■ superiority. In this paper, the basic principles and steps of the algorithm used in this program are described in brief and concise, the function of the program and the significance of the process and identifier used in the program are described, together with the calculation results of the source program and the example of the computer. This program is available for production practice applications, but also can be used as a “routing design” supplementary reference course.
