To investigate this problem experimentally, a hydraulic slamming system was developed in the SVA. With this system, pitching, heaving and coupled movements can be introduced with a frequency of up to 2.0 Hz and an amplitude of up to 10 cm on model ships. It can test models with a length of 5.5 m and a moving mass of 500 kg. By measuring pressure variations in the kHz range on up to 30 measurement points, local peak pressures can be identified.
