Dynamic test are mostly performed in specific test setups with adjustable boundary conditions and relevant aspects of the product environment. The dynamic characteristics of the environment and boundary condition are represented by dynamic connection elements. The Impedance, frequency depending ratio of reaction force and deflection speed, can be used to describe the dynamic properties of dynamic connection elements. In the first part of this article two demonstrator systems are introduced to explain the current challenges in dynamic testing and specify the need for a machine element with adjustable impedance. In the second part of this article the design approach and performance of the current adjustable impedance element is introduced. In the last part the planned collaboration between three research facilities is introduced to tackle the current challenges in dynamic testing by applying the adjustable impedance element to existing test setups.
