The paper presents the methodology and case study for structural weight optimization of hinges and 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. The paper discusses topology optimization parameters to reduce the weight of the existing components without compromising required stiffness and strength requirements. 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, which is converted into feasible lightweight design considering manufacturing constraints. These lightweight designs are validated for their structural strength using FEA. Existing and optimized designs are compared for weight, stiffness and strength parameters.


Automobile domain always demands reduction of weight of any component/assembly without compromising its performance parameters. It is always desired to reduce the weight of a combat vehicle, as shown in Figure 1, intending various advantages in terms of vehicle performances such as ride, handling, fuel consumption and amphibious performance. The study highlights weight reduction of existing components of ramp door assembly by exploring topology optimization technique using Finite Element Analysis (FEA). Initially, hinges and arms of the ramp door assembly are selected for the weight reduction task.
