轨道交通真空灌注部件质量问题研究

Research on Quality Problems of Vacuum Pouring Parts in Rail Transit

复合材料与铝合金等轻质金属材料相比,具有轻量化、高强度、高耐候等优点,并已经在航空、航天、船舶等领域有了多年成熟的应用经验。所以,随着节能减排环保意识的不断增强及相关法律法规的出台,复合材料成为解决轨道交通装备轻量化问题的最佳选择。本文以轨道机车某部件为例,对复材真空灌注工艺基本原理、影响因数、工艺过程中常见的质量问题进行分析。

Compared with aluminum alloy and other light metal materials,composite materials have the advantages of lightweight,high strength and high weather resistance,and have many years of mature application experience in aviation,aerospace,shipbuilding and other fields.Therefore,with the increasing awareness of energy conservation,emission reduction and environmental protection and the introduction of relevant laws and regulations,composite materials become the best choice to solve the problem of lightweight rail transit equipment.In this paper,taking a part of railway locomotive as an example,the basic principle,influence factors and common quality problems in the process of composite vacuum pouring process are analyzed.
