Besides the actual analysis and dimensioning of lightweight structures there is an ongoing development, construction and operation of specialized test rigs. Over time a number of test rigs have been constructed, partly in cooperation with other institutes. These test-rigs are utilised in the different fields of application and facilitate the implementation of hydraulic-, material- or componnent-test or highly specialised tasks like the simulation of deep-sea conditions. Besides the Hexapod, a servohydraulic six-axes test-rig that enables multiaxial static as well as dynamic operations, there are numerous other test-rigs. Details about them can be found in the section equipment.
