The Impact

Proposal the medium filling scheme of LNG tank container impact testing that filling the tank with water which mass is equal to dangerous goods, since the medium filling scheme before is difficult and loss, by finite element calculation with ANSY to the stress of LNG tank framework in the actual conditions and test conditions. Studies show that the two conditions of the tank is similar, test conditions can simulate the actual filling conditions. Applying this conclusion to the impact test, which can greatly simplify the test procedure and reduce the difficulty of the test, the test can be enhanced operability and economy.

This paper adopts universal finite element calculation software to carry out finite element analysis for Tianerya trench-buried inverted siphon. Researching variation law of the inverted siphons stress and displacement in construction process and operational process. The calculation results further shown design schemes rationality and safety. The analysis results provide a certain reference for design of trench-buried inverted siphon structure.

The Impact

The impact specimens with different hydrogen contents were solution treated at 540±3°C for 12h; water quenched at 60-100°C; and aged at 165±1°C for 6h. The impact test was carried out at Roell450 pendulum impact testing machine. The impact test results show that the impact energy has strong relation with the hydrogen content. The total absorption energy increases with the increasing of hydrogen content. The crack propagation energy Avp and present larger proportion than the initial crack energy Avi in the total absorption energy Av. The number of the pinholes increases and the pinholes turn from smaller irregular ones into sub-circular shape ones. The specimen with irregular sub-circular pinholes has larger KI, and has more crack propagation resistance.

Divergence Instability

The titled problem is studied numerically by finite element calculation and analytically by three-mode eigenfunction expansion. It is found that divergence instability of the coupled system is induced only when two times the number of nodal diameters 2n is equal to a multiple of the number of stationary springs N, but n itself is not a multiple of N.
