将偏角法实测数据转化为坐标法需要的坐标数据,分别用偏角法和坐标法计算各自的拨距值,并将两拨距值进行对比分析,从而得出渐伸线法计算的误差大小。同时通过计算两种方法的拨后正矢,分析其差值的规律,进而得出了一些有益的结论,对曲线整正计算方法的改进有一定的借鉴意义。 The measured data of the deflection method were transformed into the coordinate data needed by the coordinate method. The deflection distances and the coordinate method were used to calculate their respective distance values, and the two distance values ​​were compared and analyzed to obtain the error of the involute line method size. At the same time, by calculating the backward vector of the two methods, the law of the difference is analyzed, and some useful conclusions are obtained. It is of some reference to the improvement of the method of curve rectification calculation.
