摘要

高速列车现用的蓄电池箱主体框架主要由方管钢型材及折弯钢板焊接结构组成

结构较重。本研究针对400 km/h高速列车的轻量化需求

设计了一种以铝合金型材及折弯板为主要结构件的蓄电池箱体

实现了整个箱体结构的轻量化

有利于列车提速和降低能耗。基于Solidworks进行了铝合金蓄电池箱体的三维建模

利用Ansys Workbench软件进行了极限载荷工况下的结构强度有限元分析。同时研究了蓄电池箱在自由状态下的固有频率和振型。通过模态分析和静强度分析

验证了该铝合金蓄电池箱结构的安全可靠性。

Abstract

The frame of battery box used in high-speed train is mainly composed of square tube steel profile and welded structure of bending steel plate. Aiming at the further lightening requirement of 400 km/h high-speed train

this paper designs a battery box with aluminum alloy profiles and bending plates as the main structural parts

realizes the lightening of the whole box structure

which is beneficial to train speed-up and energy consumption reduction. Based on Solidworks

three-dimensional model of the battery box is built

and Ansys Workbench is used to analyze its structural strength under ultimate load. At the same time

the natural frequency and mode shapes of battery box in the free state are studied. Through modal analysis and static strength analysis

the safety and reliability of this new structure are verified.
