AI Technical Summary
Existing topology optimization methods cannot maintain the robustness of vibration reduction performance when the external excitation frequency shifts. Their stability and adaptability are poor, making it difficult to meet the needs of actual engineering environments.
By determining the initial minimum response frequency, using the null space method and characteristic matrix to solve the problem, and combining iterative updates of design variables with the introduction of multi-dimensional constraints, the structural topology design is optimized to achieve precise control of the minimum response frequency.
It significantly improves the stability and adaptability of the target structure in complex engineering environments. The optimized structure has a clear topology, reduces the difficulty of engineering manufacturing, gives full play to the material properties, and achieves the best balance between vibration reduction effect and mechanical properties.
