Sloshing Impact Performance Test Machine for Structures in Cryogenic Environment

摘要

A test object such as the primary barrier of a cargo hold where cryogenic fluid such as liquefied natural gas is stored is installed in a container containing liquefied nitrogen, which is a cryogenic fluid, and the impact resistance can be tested by applying a shock load to the cryogenic fluid to actually test the cryogenic environment. The present invention relates to a sloshing impact test apparatus for a cryogenic structure capable of reflecting an impact load due to sloshing under the present invention. A lifting unit installed on the main body so as to move up and down; A weight body fixed to the lifting unit and falling together with the lifting unit; An outer container installed at a lower portion of the main body, the outer container having an open top surface; It is installed at intervals inside the outer container, the heat insulating material is accommodated inside the frame of the metal material and the upper surface is opened in the form of a cylinder to receive the cryogenic fluid inside, the test object is locked to the cryogenic fluid on the lower surface A fluid storage container installed fork; And a load measuring unit for measuring an impact load generated when the weight falls and collides with the cryogenic fluid in the fluid storage container.
