摘要:
研究了基于遗传算法的黏弹性阻尼装置在结构隔减震控制中的多参数并行优化问题.同时考虑了黏弹性阻尼装置的材料性能和形状尺寸参数的组合优化,从性价比的角度提出了目标优化函数,建立了黏弹性阻尼装置参数的优化模型.以单自由度隔震结构体系为例,采用遗传算法对其进行优化分析.结果表明:在结构和造价的双重预期目标下,通过遗传算法优化分析得到,加入黏弹性阻尼装置后,结构的位移和加速度都达到了预期的效果,同时也表明遗传算法在用于多个组合参数的优化设计时是可行且有效的.
Abstract:
Parametric combinatorial optimization of viscoelastic device in earthquake isolation and mitigation of structures is investigated in this paper. Based on the balance between structural performance and construction cost, an objective function for optimization is set up, and a parametric optimization model considering parameters on both material property and shape for viscoelastic device is developed. The genetic algorithms method is used to complete the parametric optimization of a isolation model with single degree of freedom. The numerical results show that the goals of anticipated parametric optimization are achieved when viscoelastic device is installed in structures, and the effective performance of combinatorial optimization by using genetic algorithms is proved.
