An Experimental Investigation of Feature Availability in Nominally Identical Structures for Population-Based SHM

摘要: It is perhaps well known that the uncertainty in realistic structures may complicate most efforts for modelling and damage identification. In a population of which are considered identical, as wind farm example, it very often accurate one structure will be inadequate robust monitoring rest an SHM approach. This paper presents exploration common features can found nominally identical used identification with ultimate purpose population-based SHM. The concept approach means any additional new to not need fully modelled order monitored. Two different variants tail wing Piper PA-28 aircraft create two pairs by separating wings half. four thus contains them similar, but they have length weight. A full modal test performed all possible also done. results show damage-sensitive exist across structures, key requirement if successfull.
