To study the influence of the pre-tightening force of the carbon fiber composite barrel of the electromagnetic railgun on the overall performance of the barrel, this paper has built a local finite element model of the fiber composite barrel and analyzed the stress and deformation of the rail after it is prestressed based on the ANSYS element birth and death technology and the multi-step continuous solution method. On this basis, this paper has studied the stress and deformation of each part of the barrel after the electromagnetic expansion force is applied to the barrel, and the relationship between the condition for the stable operation of a form of railgun barrel and the pre-tightening force has been obtained. The results show that the appropriate pre-tightening force of the barrel is necessary for the stable operation of the railgun. The conclusions of this paper can guide railgun design.
