MEMOSIK® presents the active vibration dummy developed by Wölfel for the evaluation of the vibration comfort of vehicle seats - on vibration test stands as well as in the car during the ride.

The dummy is designed to that it simulates the vibration behavior typical for the driver on the seat, at the same time releasing the test engineer from the test person role. The methodology behind is the reproduction of a driver-typical so-called „dynamic mass“.

An intelligent feedback control system allows for the quick switch-over in MEMOSIK® between different driver groups, the so-called percentiles:

• small female (f05),
• average male (m50) and
• large male (m95).

Direct following the test drive a MEMOSIK®-measurement delivers

• the vertical seat-transfer-function, including its characteristics,
• the vibrations acting on the driver via the seat, including an assessment. 

MEMOSIK® is a physical vibration dummy, i. e. it consists of steel and electronics. Its virtual equivalent is called CASIMIR, our numerical vehicle occupant model.
