【Abstract】 The finite element analysis on horizontal assembly manufacture deformation of aluminum magnesium alloy vessel with thin wall and large diameter is performed by taking a material vessel of the high pressure polythene equipment in Maoming ethane project as an example. The calculation results and engineering tests show that the horizontal assembly and automatic welding can be made only the adequate deformation control measure is taken for manufacturing vessel with thin wall and large diameter. This paper offers a reinforcing measure of deformation control and the finite element analysis on it. The results as well as the practical engineering application show that the deformation control measure can meet the manufacture demands of horizontal assembly and automatic welding for aluminum magnesium alloy vessel with thin wall and large diameter.更多还原
