Abstract: With the gradual prevalence of liquid hydrogen in the field of the civilian applications, in addition to considering the support strength and insulation performance during the airborne transportation process, the vibration characteristics of the carrying platform have also become a key issue that needs to be urgently addressed. However, the domestic research in this specific area remains relatively limited. Therefore, this paper proposes a versatile support structure comprised of a damping module and a ball contact insulation structure. This innovative structure is designed to achieve both the support and the insulation while effectively isolating the system from external vibrations. Firstly, a comprehensive introduction to the fundamental principles and detailed structure of the flexible support structure is proposed. The primary structural and operational parameters for a prototype liquid hydrogen storage tank with a capacity of 50 L are presented. In addition, based on the dynamic theory, a damping analysis of the proposed structure is conducted. This analysis aims to determine the setting schemes for parameters such as the coefficient of spring stiffness, compression and extension travel, matching damping coefficient, and strength. The influence relationship between the spring and damping elements is determined. As a final point, a parametric structure for the support's structure is established, and the heat transfer simulations are performed. Temperature distribution diagrams for the rod assembly and its individual components are obtained. The simulation results demonstrate that the flexible support can effectively reduce the amplitude of external vibrations. For external frequencies greater than 5 Hz, the amplitude can be reduced below 6%. Furthermore, due to the small diameter of spring's wire of the damping module and the ball contact, thermal resistance in the supporting rod greatly increases, resulting in a low heat flux of only 22 W/m², which is about 55.1% lower than that of an equal length rigid rod in the same assembling space.
