In this article, the problem of time-dependent stress redistribution of a piezomagnetic rotating thick-walled cylinder under an axisymmetric hygro-thermo-magneto-electro-mechanical loading is analyzed analytically for the condition of plane strain. Using the constitutive equations, a differential equation is found in which there are creep strains. Primarily, eliminating creep strains, an analyt...

The buckling failure of the afterburner cylinder is a serious safety concern for aero-engines. To tackle this issue, simulation analysis was carried out by using finite element method (FEM) software to obtain mode and critical loads. It found that susceptible when subjected differential pressure or compressive force rear flange. Buckling would occur reached 0.4 times atmospheric axial on flange...

The failure of harmonic gear drive is mainly caused by the fatigue fracture flexible wheels and damage bearings. In this paper, stress sensitivity life characteristics with thin-walled vulnerable components are studied. Firstly, structure wheel a B3-80 general reducer designed, finite element model established using ANSYS software, analysis results compared theoretical calculations to verify co...

The self-tightening technology of body tube is to apply a certain pressure in the inner bore so that corresponding residual stress generated tube, and can improve situation when it use extend its service life. Most existing research for large-caliber artillery are simplified thick-walled cylinder model, ignoring internal rifling chrome-plated processing factors, impact load on cracks stresses s...
