| Abstract: | Aiming at 7075 aluminum alloy which is extensively used in aviation and astronavigation industrials through adopting ANSYS software of finite element the numerical calculation of finite element was carried out. According to the approximately calculating method of meshing element, step-by-step calculate to the true value, the feasibility of numerical simulation for the thermal process of 7075 aluminum alloy by electron beam welding was researched. The results indicate that the heat input of aluminum alloy of electron beam welding is very high, and weld is rather narrow, and the penetration is deep. By proofing test, the distribution of temperature field is obtained by means of numerical calculation of finite element and is basically consistent with the measured results. |
