摘要

高速列车轻量化在降低能耗的同时，也对其服役环境提出了更高的要求。特别是在发生火灾时，轻量化的承载结构在热力耦合作用下可能受到破坏，从而造成损失。本文以有限元理论、非线性理论和结构准静态理论为基础，建立了高速列车车体结构热耦合静强度刚度仿真分析方法，并基于ABAQUS软件提出了仿真分析技术路线。通过对某高速列车车体结构热力耦合静强度刚度仿真分析及优化，验证了该方法的实用性和有效性。

Abstract

Light weighting of high-speed trains drastically deteriorates their service environment while reducing energy consumption. In particular, in an event of a fire, light-weight bearing structure is likely to be destroyed by thermal coupling, resulting in great losses. Based on finite element theory, nonlinear theory and structural quasi-static theory, a simulation method of thermal coupled static strength stiffness of high-speed train body structure was established. With ABAQUS software, a simulation analysis technology route was proposed. The simulation analysis and optimization of static strength stiffness of thermal coupling of body structure verified the practical application of this method.
