摘要:
基于遗传算法及平板建筑构件瞬态振动响应时域有限元模型,提出一种提高平板建筑构件瞬态隔振性能的边界条件优化方法.有限元模型可模拟任意弹性边界条件下平板结构的瞬态振动响应,并在此基础上引入遗传算法,以边界条件为优化变量、瞬态振动响应最小化为优化目标,对边界参数进行最优解搜索,最大程度提升平板建筑构件对已知瞬态激励的隔振性能.实例结果表明:运用所提优化方法可以在不改变平板自身参数(材质、尺寸、厚度)前提下,通过边界条件的优化设计,有效提升平板建筑构件的瞬态隔振性能.
Abstract:
Based on genetic algorithm and time-domain finite element model for transient vibration simulation of plate-like builiding elements, a boundary condition optimization method for improving plate-like structural transient vibration isolation performance was proposed. The finite element model can simulate the transient vibration response of plate structures with arbitrary elastic boundary conditions, and then the genetic algorithm was introduced, this optimization method can take boundary conditions as the optimization variables, take the transient vibration response minimization as the optimization objective. The boundary parameters are searched for the optimal solution. The known transient excitations vibration isolation performance of plate-like building structure components was improved maximally. The results of numerical studies show the proposed optimization method can effectively improve the transient vibration isolation performance of a plate-like building structure by optimizing its boundary conditions without changing the plate’s intrinsic parameters(material, size and thickness).
