Development Of Statistical Simulation And Robust Parameter Design Optimization For A D-Grade Explosion-Proof Junction Box

The D-grade explosion-proof junction box is designed to withstand the pressure of explosion. Most of companies have focused on the development of high-value explosion-proof junction to improve the safety by considering the relationship between different explosion prevention components and safety of D-grade explosion-proof junction box. As the thickness of junction box increases, the safety will be improved. However, the manufacturing costs of junction box will increase numerously. Therefore, the primary objective of this paper is to identify the optimal settings for D-grade explosion-proof junction box structure with the high safety and low manufacturing costs. First of all, the information of sizes and the related stress and mass of junction box is conducted based on the proposed structure interpreting simulation and design of experiment (DoE). Then, the response surface methodology (RSM) is used to estimate the functional relationship between input factors and associated output responses. Finally, the optimal settings of sizes of junction box are obtained by using the weighted sum model for multi-objective optimization problem.
