| 摘 要： | 由于缓和曲线的曲率半径是逐渐变化的,无法得到其上点位坐标的准确计算公式,以往都是用级数展开进行近似计算,计算公式比较繁琐,计算结果的精度也不够高.利用CASIO编程计算器的定积分功能,能够计算出缓和曲线上点位坐标的精确数值,然后利用逐渐趋近法,可完成直线与缓和曲线交点坐标的精确解算.

| Abstract: | The accurate formula for calculating point coordinates of transition curve is difficult to get for its radius of curvature is gradually hanging,and it is calculated by series expansion method at present.So the formula is cumbersome and the results is not precise.The precise calculation of intersection coordinates of straight lines and transition curve can be obtained by using definite integral function of CASIO Programmable Calculator. |
