Structural design and simulation of exterior louver shading devices of glass domes

This study utilizes UG NX software for designing the exterior louver shading devices of the glass dome and establishes a virtual prototype. On this basis, computer-aided design tasks such as motion simulations and finite element analyses are carried out to exhibit the product’s mechanical structure, process, and performance. The finite element analysis results of louver blades demonstrate that adding several ribs can enhance the blades, which can alleviate stress concentration, lower the maximum stress and displacement values, and improve the partial pressure resistance. Thus, the product structure of louver blades is optimized, providing valuable feedback for manufacture and reducing the research and development timeline.
