The drop tower is used to investigate the energy absorption behaviour of materials, construction methods, components and structures. 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. The system is suitable for impact tests on plastics, composites and various other materials.
