Solution for the goal conflict between lightweight design, driving dynamics, drive and noise comfort in form of structurally integrated piezo-actuator applied on a rear axle assembly for active noise and vibration control.

  • Development of a robust actuator system for rear axles in vehicles based on a concept for structural integration of piezo-modules ready for series production, which are resistant against external influences (dirt, heat, moisture etc.)
  • Integration in rear axle components (e.g. rear axle frame) for a direct force transmission or as active absorber on the basis of structurally integrated piezo elements


Modeling and Simulation

  • Simulation of the electro-dynamic behavior of piezo-mechanical systems considering the interaction with the structure of the rear axle assembly.
