将单亲遗传算法应用于桥梁结构传感器优化布设。基于模态保证准则和模态能量准则设计了3个适应度函数,提出两步法采用单亲遗传算法在先对传感器进行定量计算的基础上再确定传感器的位置。通过一斜塔斜拉桥的数值模拟计算,证实了单亲遗传算法、提出的两步法及将模态保证和能量进行组合的评价准则的可行性和有效性。
Applying single parent genetic algorithm to optimize the layout of bridge structure sensors. Three fitness functions are designed based on the modal guarantee criterion and the modal energy criterion, and the two-step method is proposed to determine the position of the sensor based on the single parent genetic algorithm. Through the numerical simulation of a cable-stayed bridge, the feasibility and validity of the single parent genetic algorithm, the proposed two-step method and the evaluation criterion combining mode guarantee and energy are verified.
