Prof. Dr. Manfred Kohl (Karlsruhe)
Dr. Frank Wendler (Erlangen)

Motivation

  • Conventional damper:
    • Limited down-scaling
    • Incompatibility with MEMS process flow
  • SMA foil damper :
    • High dissipation energy
    • High work density
    • Large stress range
    • Accomodation of large strain
    • MEMS batch fabrication possible

Research Goals

  • The design of enhanced active or passive damper systems allowing for vibration control with respect to two (2D) and three (3D) loading directions
  • The development of a fabrication process for the 2D and 3D damper systems based on state-of-the art microtechnology
  • The extension of the experimental 1D test setup for the characterization of the 2D and 3D damper systems
  • The extension of the simulation model describing complex 2D and 3D loading cases in SMA film devices showing the SE, SME or both
  • The experimental characterization and simulation of the performance properties of different design variants of 2D and 3D passive and active damper systems
  • The development and assessment of mixed active /passive damper systems
  • The integration of temperature and acceleration sensing as well as intrinsic position sensing for smart damping

Work Package
