Embodiment 1
[0031] The application environment of the stainless steel metal hydride hydrogen storage tank is a 25°C water bath environment, which is placed horizontally. The length of the straight cylinder section of the hydrogen storage tank is H=330mm, the inner diameter r=125mm, and the outer diameter d=133mm. The hydrogen storage tank is filled with XY 2 Type hydrogen storage alloy, the alloy filling rate is 54%, the total hydrogen storage capacity is about 2500L, and the rated working pressure is 4MPa.
[0032] Stress-strain testing of stainless steel metal hydride hydrogen storage tanks includes the following steps:
[0033] (1) Select the strain point of the test
[0034] Place the hydrogen storage tank horizontally, as in figure 1 As shown in -b, a straight line L is drawn in the upper part, the middle part of the side and the lower part along the axial direction of the hydrogen storage tank. 1 , L 2 , L 3 , and then draw a straight line L in the vertical axial direction at t...
