Investigation on mechanical behavior of composite electromagnetic gun barrel based on the high tension winding

摘要

In this paper, a design of the non-axisymmetric composite electromagnetic gun barrel is proposed. A finite ele-ment model is established to simulate the mechanical behaviors of the composite electromagnetic gun barrel based on equivalent temperature cooling method. In the process of analysis, the effect of fiber tension, curing times and interaction between each composite layer are discussed. The results show that with increase of fiber layers, the fiber tension of inner layer will be released continuous, and the trend also exists between pre-cured layers. When winding layer is 118, the maximum radial displacement of the core is 0.549 mm under the action of electromagnetic repulsion (6MN). And the conclusions can be used as a reference foe design of composite electromagnetic gun barrel.
