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.
