Abstract

The most critical component of an LNG vehicle is the gas cylinder. And cylinder is a low-temperature and adiabatic pressure vessel. When heavy-duty trucks are driving on the road, the gas cylinders are subjected to various shock loads and vibrations from the road, and can cause fatigue damage due to the influence of cyclic stress during long-term driving. In order to solve these problems, this project conducts static strength analysis and modal analysis of gas cylinders based on finite element theory. In this project, Soildwork software is used to establish a solid model of the gas cylinder framework. Hypermesh processing mesh and pre-processing; Abaqus solves static strength analysis and modal analysis. The results show that the stresses are mainly concentrated in the weld and component joints. The first-order modes are all above 25Hz, but they are very close. The recommendation given for the above situation is to strengthen the head thickness and weld width.
