辙叉

提高钢的洁净度，加入Ni，Cu等耐腐蚀元素和进行微合金化提高钢的抗断裂韧性是防止辙叉表面剥落的主要措施。

Increasing cleanliness of steel , adding anti - corrosion element Ni and Cu and microalloying of steel are main measures to prevent frog surface spalling .

剪应力700MPa，作用深度1.5mm，剪应力加速铁路辙叉表面剥落。

And shearing stress was 700 MPa with depth 1 . 5 mm which accelerated the surface flaking and spalling of railway frog .

按照客运专线18号道岔设计参数并采用Rheda型无碴轨道结构建立模型，模型中对上部钢轨结构的尖轨和可动心轨辙叉部分进行了简化处理；

The model was built according to the design parameter of the 18th rail switch of the Passenger-Dedicated Lines .

采用IPC-PLC联机控制技术，使该机床具有六自由度闭环控制、辙叉水平找正、轮缘槽对刀、自动磨削/手动磨削等功能。

Using IPC-PLC control technology , the grinder took on six freedom closed control , horizontal adjusting , groove adjusting , and manual / auto-machining , etc.

本文采用手工电弧焊的方法，采用增加过渡层、U形坡口对称焊的方式，钢轨侧过渡层金属为Ni-Cr-Mo系材料，辙叉侧过渡层与焊缝金属为Mn-Cr-Ni系材料。

The SMAW method was used to solve those problems by increasing the thickness of the intermediate layers and using U groove symmetrical welding . The intermediate layer of rail sides was Ni Cr Mo alloy system , and that of frog side was Mn Cr Ni alloy system .
