Research on optimal arrangement method of carbon fiber composite fiber sensor based on improved GWO algorithm

When using optical fiber sensors to monitor the health of carbon fiber composite structures, it is necessary to study the optimal arrangement of fiber optic sensors on composite structures. According to the performance characteristics of the composite structure, a finite element simulation model was constructed, and the weak position and modal mode shape matrix of the model were obtained by analyzing the modal changes of the model. Based on the Modal Assurance Criterion (MAC) criterion, the modal order and the number of sensors are optimized, and the target modal matrix required for sensor arrangement is obtained. Finally, based on the improved Gray Wolf Optimizer (GWO), an optimal arrangement model of optical fiber sensor was proposed, and the optimal arrangement scheme of the sensor was obtained.
