Goals and idea

The basic function of the drop tower is to transport a test specimen or a defined weight attached to a ram to a height level, to release it there in a controlled manner and to drop it along a linear guide onto a test specimen or impact surface. The resulting short-term impact makes it possible to assess how energy is absorbed by materials, designs, components and structures in the event of a crash and which (low and high frequency) crash signals are generated.
