In collaboration with some of the German automotive industry OEMs, an active vibration dummy called MEMOSIK V, was defined in response to their specific requirements for vibration comfort. The topics described in this paper shall deliver an insight into a selection of the development phases of this development project. An active, three-dimensional vibration dummy is described with the newly developed MEMOSIK V, which simulates the human dynamic behavior by reproducing an equivalent dynamic mass. This vibration dummy qualifies for replacing the occupant as a test object and measuring instrument and allows the objective and repeatable measurement of the vibration transmission from the vehicle base to the buttocks and the back through the vehicle seat. Based on extensive measurements of the dynamic mass of the sitting man in the fore-and-aft, the lateral and the vertical direction, the objective functions of the vibration dummy are deduced through a modal identification approach. By integrating these parameterized functions in the control system, the dynamic behavior of the dummy can be adapted to the mass percentiles F05, M50 and M95, as well as to individual people by the software managed modification of the controller setup. The variation in posture is guaranteed for the complete design range of passenger car and commercial vehicle seats. The integrated measurement system permits the objective and repeatable rating of the human exposure. Mechanical vibration and shock - evaluation of human exposure to whole-body vibration - general requirements as well as the evaluation of seat transfer functions considering all three directions in space, both on simulator platforms and in mobile use on the road.
