2501 Inverse Analysis of Distributed Load with Strain Sensors

Abstract

Structural health monitoring (SHM) is an important and challenging technology to aim at the next generation of aerospace vehicles. The key issue is to determine the operational stress on real time which enables us to manage the structural integrity and air-worthiness. In our previous work, we reported the technique to identify distributed load, such as the aerodynamic load, by measurement data. This technique is based on an inverse interpolation method using results from a Finite Element Model (FEM). In this study, we evaluated the characteristics of this inverse analysis by the simulated model.
