ANSYS有限元法在测长绝热真空腔二维热分析中的应用
Two-dimentional Thermal Analysis of Adiabatic Vacuum Chamber with ANSYS Finite Element Simulation
摘要
Abstract
According to the difficulties of measuring temperature distribution in the adiabatic vacuum chamber, the method of combing ANSYS finite element simulation with experimental study is proposed. ANSYS finite element modeling, parameter identification, meshing, applying loads, and the solution process are described. Simulation results show that changes in ambient temperature 1℃ , heat insulation vacuum chamber temperature will change 0. 085 ℃, and verify the simulation results of the experiments. Test results show that use of the simulation can be accurate and reliable analysis of insulation vacuum chamber temperature, and improve test efficiency and reduce experimental costs.关键词
