123121 - Prediction of Burst Pressure for Type Iv High-Pressure Hydrogen Storage Vessel Based on Adaptive Meshing Method 

Abstract:

With the growth of the hydrogen energy industry, cost-effective and highly reliable high-pressure hydrogen storage technologies have gained increasing attention. High-pressure hydrogen storage vessels with plastic inner liners and composite materials (Type IV hydrogen vessels) inherent advantages such as high hydrogen storage density, corrosion resistance, and great fatigue performance, making them one of the most advanced high-pressure hydrogen storage methods. Burst pressure is a critical performance indicator for Type IV hydrogen storage vessels. Due to the complex structure of Type IV high-pressure hydrogen storage vessels, material property variations in different parts, multiple failure modes for composite materials, and substantial influencing factors, experimental testing for structural design and performance optimization is challenging, time-consuming, and expensive. The numerical simulation method is an adequate way to reduce development costs. With the progressive damage method, burst pressure can be precisely predicted. However, the finite element model has an excessively high degree of freedom, resulting in low computational efficiency.

In response to the need for precise and efficient performance simulation of Type IV high-pressure hydrogen vessels, this paper proposed a framework to effectively reduce the resources needed for finite element calculations on multiple lay-up schemes based on an adaptive meshing method. Finite element models that include the fiber orientations and geometric details on dome parts and cylinder part are established. Various damage modes are considered and coupled with the progressive damage method. Comparative analysis of different meshing methods has been carried out to study the influence of meshing parameters on the calculation speed. With data processing and programmable finite element software, a burst pressure prediction method for Type IV hydrogen storage vessels based on adaptive meshing is proposed. Burst tests have been further taken, which indicate that the numerical results match the experiment well. Meanwhile, the adaptive meshing method significantly improves calculation speed and with satisfying accuracy. In conclusion, the framework proposed in this paper not only offers valuable insights into data collection speed for Type IV hydrogen storage vessels with complex lay-up schemes but also advances the utilization of numerical simulation in the domain of hydrogen energy storage and transportation equipment.
