液氢储罐支撑结构关键技术与展望

The types，materials，and applications of supporting structures for liquid hydrogen storage tanks are systematically reviewed and analyzed. The advantages and disadvantages of various struts are comprehensively evaluated，followed by a scenario-based analysis of the supporting structures used in liquid hydrogen storage tanks during the transportation of tank trucks，ships，aircraft，and rockets. Based on the current research status，the usage types of struts exhibit distinct scenario-specific characteristics，with rod supports being the most frequently selected structure. In terms of materials，composite materials demonstrate significant potential due to their excellent thermal insulation，anti-corrosion，and mechanical properties，and are currently in a phase of rapid development. Furthermore，as the application scenarios of LH₂ storage tanks expand，thermal insulation is no longer the sole concern. Particularly in mobile storage tanks，the energy transfer resulting from vibration and shock，as well as its impact on structural strength，requires special attention.
