AI Technical Summary
Traditional structural optimization methods face problems such as fuzzy boundary descriptions, numerical instability, high computational costs, and low computational efficiency when dealing with explosion and impact loads. In particular, they are difficult to effectively handle complex topological forms and rapid iterative design in nonlinear dynamic topology optimization.
By combining the Equivalent Static Load Method (ESLM) and the Moving Deformable Component Method (MMC), the nonlinear dynamic problem is decoupled into a linear static problem by establishing a mapping relationship between the dynamic displacement field and the static load field. Furthermore, through the explicit topology optimization framework of MMC, efficient and clear geometric boundary optimization of the structure is achieved.
It enables the rapid exploration of structural configurations with high stiffness, lightweight and excellent impact resistance within a broad design space, improves optimization efficiency and the engineering feasibility of the results, and enhances the structure's resistance to damage under extreme loads.
