System Reliability

The Research Group SAM is researching the methods of characterizing, evaluating, and controlling uncertainty in load-carrying structures in mechanical engineering within the framework of the Collaborative Research Centre SFB 805.

  • Load monitoring: In subproject C1 of the SFB 805, the algorithms for determining the loads and the changes to system properties are being expanded. These algorithms are for the applications already in place, and structurally characterize, evaluate, and finally control arising uncertainty.
  • Active stabilising technologies: Subproject C2 deals with controlling uncertainty in the use of actively stabilized structures. The focus is to prevent a buckling failure of an axially compressed column by using active technologies and to, therefore, control the uncertainty in the load.
  • Assessment of structure-property-relations in active systems: In subproject C3, the uncertainty in the property’s variances of an entire, load-carrying system is controlled. A method is being developed for quantifying and characterizing the uncertainty found in the interaction between the passive and active system elements.
  • Variable processes and application of methods and technologies for uncertainty control in load-carrying systems: In subproject C5, the uncertainty that occurs in the development, production, and usage of load-carrying systems is described and assessed as a result of both a variable process modelling and application through use of the SFB-Demonstrator.
  • Structural health control of load-carrying mechanical systems: In subproject C7, the uncertainty in the predicted lifetime, caused by collapse or impairment, of mechanical systems is controlled, on one hand, through autonomous approaches of Structural Health Monitoring (SHM) and, on the other hand, through the autonomous dynamic intervention of Structural Health Control (SHC).
