Manufacturing Of Lightweight Embossed Sheet Metal Canister

Abstract

square shaped sheet metal embossed canister is required to house the article during its loading, transportation, articulation and handling. It is a hollow, square cross sectional structure, internally pressurized system to store as well as hold the article during articulation and transportation. For this manufacturing technique proper lightweight material is need to be select. By considering various parameters affecting the canister material proper material is selected by the FEA method. Also considering this canister system launches its missile from inside hence lot of plume pressure and temperature is generated inside the canister. To overcome this proper material is need to be select. FEA is done in Abaqus software with different load cases like upper canister fire, lower canister fire. The canister is to be manufactured using sheet metal which is embossed to increase the stiffness and strength of the canister. Initially the sheet metal is embossed using a high die punch on a Hydraulic press, and then it is bended at two locations to form an inverted U type top section. Similarly matching U type bottom section is made. Now both the top and bottom sections are welded to form the square cross section of the canister.
