Abstract:
The problem of contact interaction of elements of the electromagnetic accelerator barrel is solved. Two-dimensional elastic approximation is used. Design area is one fourth of the cross section, area includes rail, insulator and overwrap. To solve the problem, a twolevel Schwartz additive method is used, using which the problem in the entire domain is reduced to solving a number of local contact problems in the entered sub- domains. The results of 3 calculations are presented: the first calculation used realistic orthotropic properties of materials, the other two calculations used isotropic approximations (for minimum and maximum values of Young's modules). Comparative analysis of stressstrain state of accelerator barrel for each case was carried out.
