| Abstract: | Flanged connections are widely used in a rocket engine.We propose a new method for calculating the load and deformation of such components as bolt-shaped rings and flanges which are regarded as integral components and subjected to external load.The calculation results of a numerical instance show that the calculation method proposed in this paper produces more realistic results than those produced by the equivalent pressure method. |
