Abstract
The present disclosure discloses a testing apparatus for directional simulation of dynamic collision between a deep-sea shell structure and seabed, including: a launching device, a high-pressure water pump device, a high-speed camera, a sensor system, a data collection and control system, etc. This device is installed in a geotechnical centrifuge for experiment, a super-gravity environment is provided to meet requirements of simulation of a deep-sea environment, and a deep-sea high-pressure environment is created through a high-pressure water pump device by superposition. A direction of the launching device is adjusted through a universal rotating shaft to control the shell structure to be launched from a specified direction to collide with soil at a predetermined position. A high-speed camera is used to capture an entire experiment process, and strain and acceleration sensors are used to collect experiment data.
