Abstract

The invention discloses an LNG (liquefied natural gas) marine insulation tank pressure-bearing test device which comprises a lower pressing plate and an upper pressing plate. The length of the lower pressing plate is larger than that of the upper pressing plate, a first buffer gasket is laid on the lower pressing plate, an insulation tank is place on the first buffer gasket, a second buffer gasket is laid on the upper surface of the insulation tank, a pressing heat is placed on the second buffer gasket, two displacement sensors are mounted on two side surfaces of the upper pressing plate respectively, wires of each displacement sensor are connected to a strain signal acquirer according to orders, and distance and time signals are transmitted to the corresponding strain signal acquirers by the displacement sensors. According to an LNG marine insulation tank pressure-bearing test method, force-displacement curves and strain data are acquired, correctness of theoretical design of the insulation tank is verified, designed theoretical curves of the of the insulation tank are acquired, design cost is reduced, design process and manufacturing time of the insulation tank are remarkably improved, and the construction period of an LNG ship is further shortened.

Description

technical field [0001] The invention relates to the technical field of pressure-bearing test of an insulating box for LNG ships, in particular to a pressure-bearing test device and a test method for an insulating box for LNG ships. Background technique [0002] LNG ships are the pearls of the shipbuilding industry, and their construction is notoriously difficult. According to the technical status of domestic shipyards, there are many construction difficulties that need to be overcome, and the construction of liquid cargo containment system is one of them. The insulation tank is one of the core components of the liquid cargo containment system. However, the design of the insulation tank is done by foreign companies. There are no shipyards and design units in China that fully control the design of the insulation tank. The initiative is almost always controlled by foreign companies. company. Now, the competition in the shipbuilding industry is becoming more and more fierce. E...
