2.尖轨长度的计算单开道岔采用曲线型尖轨时,尖轨长度必须满足其与基本轨之间的轮缘槽 t_(min)≥66～65毫米(分别为60及50轨道岔的要求)。若假定尖轨是刚体,则从尖端至迥转中心的长度 l_o 即可根据转换条件确定。(1)单半径圆曲线型尖轨,与基本轨平面连接为切线型并在尖轨顶宽5毫米断面前斜切,由图7,可列出: 2. The calculation of the length of the sharp rail single-turnout curve-type sharp rail, the sharp rail length must meet the basic rail flange groove t_ (min) ≥ 66 ~ 65 mm (respectively 60 and 50 rail switch Claim). If it is assumed that the sharp rail is a rigid body, the length l_o from the tip to the center of rotation can be determined according to the transition condition. (1) Single-radius circular curve type sharp rail, connected with the basic rail plane as a tangent type and bevelled 5 mm wide at the top of the sharp rail rail, as shown in Figure 7,
