As one of the core subsystems of fuel cell vehicles,the on-board hydrogen system,once subjected to a large extrusion pressure in traffic accidents,may lead to the failure of key compo-nents,resulting in a large amount of hydrogen leakage,which may lead to more serious consequences,so the evaluation of the extrusion resistance of the on-board hydrogen storage cylinders is an important task to further improve the safety evaluation system of fuel cell vehicles.This paper establishes a squeeze evaluation method for on-board hydrogen storage cylinders,describes in de-tail the four aspects of the squeeze evaluation method,and carries out the squeeze test verification of on-board hydrogen storage cyl-inders,analyzes the impact of squeezing on the hydrogen storage cylinders through the test data,and quantitatively evaluates and analyzes the safety of the hydrogen storage cylinders after squeez-ing,so as to provide a reference for the safety evaluation of the on-board hydrogen system.
