摘要

ANSYS作为有限元分析软件,在热分析和结构分析方面具有强大的功能。本文基于ANSYS热分析功能,选用SOLID90单元,对换热器换热管进行热分析,得到换热管的温度分布,并将计算得到的温度作为温度负荷,用弹性法求解热应力,得到换热管的轴向应力分布。根据温度分布和应力分布,提出了合理、经济的换热管制作措施。

Thermal Analysis and Stress Analysis of the Heat-Exchange Pipe Based on ANSYS
ANSYS to be as a finite element analysis software has powerful features in thermal analysis and structural analysis. Based on ANSYS thermal analysis function, this paper selects SOLID90 unit, for thermal analysis on the heat-exchange pipe of heat exchanger to obtain the temperature distribution, and the temperature calculated will be treated as temperature load, in order to solve the thermal stress by the elasticity method and to get the axial stress distribution of the heat-exchange pipe. According to temperature distribution and stress distribution, this paper puts forward reasonable and economical measures to make the heat-exchange pipe.
