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。
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.
