一、前言 近年来,由于多头捣固机工作效率的提高,线路技术状态也有所提高。虽然线路高低比较好,可是方向还不够理想。 关于曲线整正方面,有针对离心力的超高的调整和针对形状变化的圆度的整正。本文仅就以整正曲线圆度为重点予以论述。 I. Introduction In recent years, due to the improvement of the working efficiency of bumping machines, the technical status of the lines has also been raised. Although the line level is better, but the direction is not ideal. With regard to curve alignment, there is a very high adjustment for centrifugal forces and a correction for the circularity of shape changes. This article focuses on the roundness of the orthorectified curve.
