摘要

高速列车用轴箱体主要采用球墨铸铁制造,结构较重。针对400 km/h高速列车的轻量化需求,基于铝合金材料的成型特性重新设计了轴箱体结构,并采用CERO 3.0建立了铝合金轴箱体的三维模型,依据EN13749-2005标准,采用ANSYS Workbench分析了铝合金轴箱体在超常载荷工况和运营工况下的应力状态和疲劳强度。通过静强度和疲劳强度分析,验证了铝合金轴箱体结构的安全可靠性。

Abstract

The axle-box body of high-speed train is mainly made of nodular cast iron with heavy overall quality.According to the lightweight requirement of 400 km/h high-speed train,the axle-box structure is redesigned according to the forming characteristics of aluminum alloy materials. The three-dimensional model and finite element model of alu-minum alloy axle-box is established by CERO and ANSYS,respectively. Based on the EN 13749-2005 standard,the stress state and fatigue strength of aluminum alloy axle-box under the super load and operation conditions are analyzed by ANSYS Workbench. Through static strength and fatigue strength analysis,the safety and reliability of aluminum alloy axle-box structure are verified.
