Deep sea structure vibration testing method based on underwater high-speed camera

Abstract

The invention discloses a deep sea structure vibration testing method based on an underwater high-speed camera, and relates to the technical field of underwater imaging and structural dynamics testing. The method comprises the steps of installation of a deepwater sealed cabin main body of a high-speed camera, installation of a heat dissipation supporting seat, installation of a light supplementingsystem integrated base and sealed cabin internal anomaly detection, and the installation of the deepwater sealed cabin main body of the high-speed camera comprises the following steps that the deepwater sealed cabin main body comprises a sealed cabin section, a front cabin and a rear cabin; and when the front cabin assembly and the rear cabin assembly are installed, rubber ring groove areas needto be cleaned, and foreign matter such as particles cannot exist. According to the deepwater sealed cabin structure of the high-speed camera, the heat dissipation problem of the high-speed camera is guided to the sealed cabin section through the heat dissipation base structure and the heat dissipation fins, and cooling of the high-speed camera during working is achieved. By monitoring the temperature, humidity and air pressure in the sealed cabin, the high-speed camera can be ensured to carry out vibration test on the underwater structure for a long time.

Description

technical field [0001] The invention belongs to the technical field of underwater imaging and structural dynamics testing, in particular to a method for testing vibration of deep-sea structures based on an underwater high-speed camera. Background technique [0002] With the increasing demand for deep-sea weapons and equipment, it is urgent to conduct working modal tests on structural parts of key parts such as underwater weapons and equipment. However, the existing vibration test devices still use contact measurement tools such as acceleration sensors. For the complex situation of the coupling effect between the structure and the fluid in the underwater structure test, the experimental measurement is difficult, and the key parts are not easy to install. The existing The invention of underwater cameras is mostly based on the imaging requirements of ordinary cameras. Due to the low acquisition frame rate of the camera, there is no need to consider the heat dissipation of the c...
