Invention of Multi-Objective Optimization Method in Camera Structure (Calculation of Pareto Optimal Solution by Topology Optimization)

Abstract

In this research, topology optimization is performed for each purpose on a simple 3D shape in order to find the optimal camera structure in terms of structural strength and natural frequency. When performing topology optimization, we investigate how the optimum structure changes by changing the optimization conditions, and what difference there is in the evaluation of the optimum structure. As a result, in the structural strength optimization, a trade-off relationship is confirmed when the weighting conditions are changed under multiple load conditions. In multi-objective optimization of structural strength and natural frequency, even if weighting is changed significantly and topology optimization is performed, there is no significant difference in evaluation values and there is no trade-off relationship. Further, it can be seen that the structural strength is not improved.
