Abstract

Valuable information about how a dynamic system’s parameters vary is encoded in changes to the shape and size of its system attractor. Being able to analyze attractor deformation to infer system changes is thus important in many applications, such as damage detection and structural health monitoring. This work presents experimental validation of a geometry-based method for analyzing attractor deformation called Boundary Transformation Vectors (BTVs). Mass added at two locations on a vibrating cantilever beam is identified using BTVs, demonstrating that BTVs can be useful for monitoring small structural changes in physical systems.
