Sequential designing process in comparison to volume-constrained topology optimization for fundamental frequency based on FEA

Topology Optimization (TO),Weight reduction,fundamental frequency,Fuel tank stand

In this article, we put forward comparison of two method to answer a large-scale three-dimensional optimization problem where goals are maximizing natural frequency and reducing weight of fuel tank stand. Optimization of any structure with complex features can be a very memory hungry task for computer and more often results of these optimizations are not accurate due to potentially conflicting objectives.
Both approaches compared in this article have their ups and downs, first method is testing natural frequency and adding support and reducing weight from area with least deformation, 2nd method is based on topology optimization feature available in abaqus software. In both approaches, optimization of a fuel tank stand with goal of maximizing naturel frequency and reducing weight is the centre of focus.
