Constructive Elements Stress Analysis of Deuteron Cyclotron DC-1 Magnetic System

摘要

The stress problem is calculated for structural elements of the magnetic system of the four-sector deuteron cyclotron with superconducting current coils. Possibilities to use stainless steel and aluminium alloy as constructive materials are analysed. The size for bandage, yoke and other elements is chosen on the basis of the preliminary developed scheme for division of the current coil into sections and design of each section. The calculations have been made on the computer using the method of finite elements on the two-dimensional triangle net. The problem of stress theory is solved for the flat stressed state with allowance for distribution of pondermotive forces over the knots of the net, and stresses occurring due to thermal deformations. Distributions of displacements and the main stresses over the problem region are calculated for two mutually perpendicular cross sections of the current coil section. The size of structural elements are chosen in the way that their bends do not exceed 0.03 mm for aluminium alloy and are insignificant for stainless steel. The main stresses are within the permissible limit; hence the given magnet design allows one to use both constructive materials. 5 refs.; 7 figs.; 3 tabs. (Atomindex citation 17:055237)
