铁道货车用等温淬火球墨铸铁斜楔标准综述

Summary of Austempered Ductile Iron(ADI) Wedge Standard for Railway Wagons

在概述我国铁路货车主型转向架摩擦减振器斜楔及其标准发展过程的基础上,详细介绍国际标准化组织、美国、欧洲和我国关于球墨铸铁件标准的变化过程。为正确理解与实施TB/T 2813—2015《铁道货车摩擦减振器斜楔》,从标准修订原则和依据、主要变化内容、材料命名等方面,说明TB/T 2813—2015与TB/T 2813—1997《铁路货车摩擦减振器球墨铸铁斜楔技术条件》的主要区别。

By introducing friction shock absorber wedges applied to the main types of bogies for domestic railwaywagons and the development process of its standard,the paper give a detailed description of the evolution process ofnodular iron casting standards developed by ISO,the USA, Europe and China. To properly understand and imple-ment Standard TB/T 2813—2015 Friction Damper Wedge for Freight Car,the paper states the main differences be-tween TB/T 2813—2015 and TB/T 2813—1997 Technical Specifications for Friction Damper Wedge of Ductile Iron for Freight Car.
