Abstract

The study involves a finite element analysis to evaluate the structural integrity of the neck mount block for a type 4 hydrogen storage vessel, with the aim of enhancing its strength and rigidity. The existing neck mount block consists of a fixed part and a sliding part, each comprising a body block for load support, a screw part for neck boss fixation, and bolts. To analyze the vulnerabilities of the neck mount block under bolt fastening and load conditions relative to vehicle travel directions, a structural analysis process was developed. Comparative analysis between the enhanced design and the existing model was performed, resulting in improved strength and rigidity. The objective is to provide guidance for the current product development and to offer fundamental data for the design and structural analysis of future development projects.
