摘要
基于模态置信度MAC准则,通过建立优化约束条件及目标函数,构建完整的优化数学模型,引入模拟退火算法的抽样和退火过程,使系统能量逐渐降低并达到新的平衡点,如此反复获得模型最优解,基此建立传感器优化配置法。通过某拱塔斜拉桥主梁加速度传感器优化布置工程的实例分析,证明基于MAC准则的模拟退火算法在求解传感器优化布置上,具有优良的并行性和搜索全局的功能。
Based on MAC criterion,this paper tries to establish optimized layout method for sensors through constructing optimal constraint conditions,object function and integrated optimal mathematical model,further to constantly search the optimal solution of which using sampling and annealing of simulated annealing algorithm to reduce system energy to reach the new balance. Meanwhile,simulated annealing algorithm based on MAC criterion is proved to possess the virtue of well parallelism and seeking overall functional via an engineering instance analysis of acceleration sensors optimal placement for an arch tower cable-stayed bridge.
