题目An Efficient Approach for the integration of a Structural Health  Monitoring System in Smart Structures

报告人Prof. Kai-Uwe SchröderFull Professor in the Faculty of Mechanical Engineering at the  RWTH Aachen University





High performance at lower weight is the main challenge of recent  structures in automotive and aerospace applications. A failure of these high  performing parts will be catastrophic as no more structural reserves can be  activated after exceeding limit load or service goal due  to the optimization of the parts. Hence, the  monitoring of the structural integrity of such high performing structures  becomes vital. As scheduled inspections increase costs, to establish a  Structural Health Monitoring (SHM) system which is running during service is the  goal. This system has to be reliable, durable and efficient, as the structure’s  integrity has to be assessed in runtime.

    In this talk an SHM  approach will be presented which is based on the intensive use of structural  information of the sizing process. With this information specific Structural  Damage Indicators (SDI) are derived which are monitored. As not the damage  itself but the Structural Damage Indicator is the object of interest the design  of the SHM system can be optimized in terms of accessibility, reliability and  sensitivity. In addition to this the structural integration of the SDI  monitoring sensors is possible which offers new opportunities in terms of  robustness. At RWTH Aachen University a network of 15 institutes is following  this approach. The collaboration results in a first composite part with an  integrated SHM system which demonstrates the feasibility of the presented  approach.


Prof. Dr.-Ing. Schröder graduated in civil engineering in 1999 at  Leibniz University Hannover. In 2005 he completed his PhD thesis at the  Institute of Structural Analysis of Leibniz University Hannover. Subsequently,  he worked as a senior engineer and project manager at the ELAN GmbH Hamburg, now  ELAN-AUSY, being in charge of the method and tools development for the Airbus  research projects of the A380, A400M and A350 programs. In 2010, he became  Assistant Professor at the Institute of Constructional Lightweight Design at the  Johannes Kepler University of Linz, Austria. In 2013, he became a full Professor  at RWTH Aachen University at the chair of engineering mechanics and since August  2014 he is Professor at the Institute of Structural Mechanics and Lightweight  Design. He is a full member of LTH Structural Analysis (IASB) since 2006.  His main field of interest comprises Methods  & Optimization, Dynamics & Aeroelasticity, Structural Durability &  Structural Health Monitoring as well as Space Structures.
