电流变夹层板的拓扑优化研究

TOPOLOGY OPTIMIZATION OF SEMIACTIVE VIBRATION CONTROL FOR AN ELECTRORHEOLOGICAL SANDWICH PLATE

  • 摘要: 为了优化电流变夹层板中的变刚度控制效果,对其进行了夹层结构的拓扑优化。首先,基于变刚度控制效果的分析,确立了结构的单阶模态和综合模态频率变化率为优化目标,然后基于粒子群优化算法对结构进行了拓扑优化,并且给出了相应的拓扑构形。最后,采用变刚度控制的等效阻尼比和时域响应对比两种手段对拓扑优化的结果进行了验证,两类验证都表明这些优化的拓扑构形能在较小的材料利用率下,可以取得较好的变刚度控制性能。

     

    Abstract: Topology optimizations for an electrorheological sandwich plate under semiactive variable modality stiffness vibration control are investigated. First of all, on the basis of topological particle swarm optimization (PSO) and taking the needed amount of electrorheological (ER) material and the maximization of semiactive control ability as the objective function, the topological optimization design method of damping structure was presented, and the topological configurations of maximizing a single or multiple modal frequency mobility of the ER sandwich plate structure under certain needed amount of ER material were obtained. Subsequently, the comparisons of equivalent modal damping ratio and time responses with the optimal configurations and fully covered layout validate the effectiveness of the proposed semiactive controller and topology optimized approach.
