Sinopsys - Model based structural monitoring using in-operation system identification

From 01-10-1997 to 30-09-2000

Description

The project's main objective is to develop, implement and validate methods to estimate a structural dynamics model from in-operation measured data. Such models are not only expected to describe the actual dynamic behaviour more accurately than laboratory model test models, in many cases they are the only ones which can be estimated. The application of such models will be investigated for the following problems: - to improve the reliability of response predictions to actual loads - to improve the accuracy and reliability of numerical (FEM - Finite Element Method) models - to permit the monitoring and diagnosis of the structural behaviour during the product life - to optimise the design and performance of process control systems. To achieve these objectives, the following activities will be performed: - Feasibility assessment and requirement definition The required base line know-how for in-operation system identification will be collected. A principal evaluation will be made on how such models can be applied to the described problems (response predictions, FEM updating, monitoring and damage diagnosis). This will result in a requirement definition for further research and prototype development. - Development and enhancement of in-operation structural identification techniques
