description	The invention discloses a composite material laminate optical fiber impact position identification method based on strain nonlinear weighting, and belongs to the technical field of structural health monitoring. The method comprises the following steps of 1, arranging an OFDR distributed optical fiber sensor network; 2, acquiring an impact load response signal of an OFDR distributed optical fiber sensor; 3, according to a stress concentration phenomenon at the impact load acting point of a composite material plate structure, extracting a strain amplitude feature vector; 4, constructing a to-be-positioned sensing area through the strain amplitude feature vector; 5, establishing a strain amplitude nonlinear weighted centroid positioning functional expression, and solving to obtain an impact load positioning coordinate; and 6, optimizing and selecting nonlinear weighting times m by taking the minimum target function value of the positioning error of the sample impact point as a criterion, and recalculating the pr
