ABSTRACT = {This work aims to improve the setup of an electrodynamic triaxial
shaker prototype with respect to its usability for the automotive industry. Triaxial
shakers being capable of meeting the corresponding requirements are not
available as standard test equipment. Modifications on the fixture have to be
conducted in order to ensure an effective control. The first part of the work is
the qualitative description of the system behavior. Therefore, the shaker is treated
as a black box. The second part is the modification of the test fixture in order to
handle the resonances of the shaker, which is elementary for its usage. A setup is
found, that improves testing within the desired frequency range. Thereby,
acceleration levels are considered as well as excitation phases and coherences.
The proposed setup is used for an exemplary specimen with two different control
scenarios. Conclusions are then drawn about the usage of triaxial shakers.},
