基于Abaqus空气压缩机中间冷却器的热场分析

Thermal Field Analysis of the Intercooler for Air Compressor Based on Abaqus

利用Abaqus有限元软件对某空气压缩机中间冷却器建立数值分析模型,并结合流体的基本方程、模型方程和计算流体动力学流固耦合模块对该空气压缩机中间冷却器壳体、折流板及换热管部件的温度场和应变耦合关系进行仿真与分析。结果表明:壳体、折流板及换热管均存在不同程度的应变位移量,在安装和约束部位尤为明显;温度沿气流方向呈下降趋势,且高温压缩气体出口温度与设计温度吻合较好。

The numerical analysis model of an air compressor intercooler was established with a commercial finite element software Abaqus. Combined with basic and model equations of fluid, the CFD（computational fluid dynaxnics）fluid-solid coupling module, the temperature field and strain coupling relationship of the shell, baffles and heat transfer tubes of the air compressor were simulated and analyzed. The results show that various strain displacements exist in shell, baffles and heat transfer tubes, especially in the position of installation and restrain. The temperature decreases along the direction of high pressure air flow, and the outlet temperature of high temperature compressed air is in agreement with that of the designed.
