新型链式车钩铸造工艺设计与应用研究

Casting Process Design and Application of a New Type of Chain Coupler

新型链环连接方式车钩是一种新型差异化车钩,具有曲线横向灵活摆动的优势特征。主要应用于北美机车车辆,是机车车辆零部件系统重要组成部分。针对新型链式车钩的产品结构、设计要求、技术难点、功能需求,使用铸造CAE模拟仿真技术,优化铸造工艺设计。成功试制了新型链式车钩,通过产品检测,实现了批量供货。

The new type coupler with chain link connection was a new type of differential coupler,which had the ad vantage of curve lateral flexible swing.It was mainly used in North American rolling stock.It was an important part of rolling stock parts system.According to the product structure,design requirements,technical difficulties and functional requirements of the new chain coupler,casting CAE simulation technology was used to optimize the casting process design.The new chain coupler has been successfully trial-produced.through product testing,the mass supply has been realized.
