[0003] When the storage tank containing liquefied natural gas is moved, the liquid inside the storage tank will vibrate or the thermal expansion and contraction caused by the temperature of the liquid inside the storage tank will cause the shielding layer film structure in direct contact with the liquid to produce a displacement amount, and the displacement frequency will be very high. In order to test the mechanical property stability of the shielding layer film structure after high-frequency displacement, it is necessary to test the mechanical property of the shielding layer film structure. In actual testing, the main shielding layer is usually connected with the mechanical equipment first, and then the mechanical equipment repeatedly applies tension to the main shielding layer to cause the relative displacement between the main shielding layer and the secondary shielding layer, thereby simulating the displacement in use.
