In automobile domain, It is always demanding to reduce weight of any component/assembly without compromising its performance parameters. This research study presents methodology and case studies for structural weight optimization of hinges & arms of ramp door assembly of a combat vehicle using finite element analysis (FEA). Weight reduction of hinges and arms of existing ramp door assembly is achieved by optimal material distribution using density method of topology optimization technique as well as it discusses topology optimization parameters to reduce weight of the existing components without compromising required stiffness and strength requirements. With defining minimum compliance and mass as objective functions, the study highlights problem formulation by defining design and non-design volume for topology optimization using solid isotropic material with penalization (SIMP) technique. As an outcome, optimal material design of hinge and arm is achieved that is converted into feasible light weight design considering manufacturing constraints. These light weight designs are validated for their structural strength using FEA. Existing and optimised designs are compared for weight, stiffness and strength parameters.
