Optimal Design of the Steel Bracket Stability for Large-Scale Bag Filter

为实现某大型袋式除尘器钢支架结构的稳定性优化设计,在有限元数值分析和幂函数回归模型基础上,提出了一种基于幂函数回归模型的结构稳定性优化设计方法(SOD)。通过SOD实现了钢支架满足强度、刚度及稳定性综合性能下的轻量化优化设计。钢支架优化分析结果表明:在保证结构强度、刚度良好、稳定性不变的情况下,其耗钢量降低了10%,而在保证结构强度、刚度良好、耗钢量基本不变的情况下,其稳定系数达到了1.800,提高了18.7%。

To realize the optimal design of the steel bracket stability for large - scale bag filter, a structural stability optimization design method（SOD） based on finite element numerical analysis and power function regression model is put forward. By this method , the lightweight optimization design for steel support is realized, which the comprehensive performance, including the structural strength, stiffness and stability. Steel support optimization analysis results show that： both the structural strength and stiffness is satished, and structural stability is unchanged, its steel consumption is reduced by 10% ; both the structural strength and stiffness is satished, and basically steel consumption is unchanged, its stability coefficient reaches 1. 800, or increased by 18.7%.
