The establishment of a three-dimensional finite element model of stainless steel pipe fittings. Through stress analysis, it is found that there is obvious stress concentration on the compressed end face of the winding pipe under the condition of axial compression. It is predicted that the edge effect of the compressed end face of the pipe fitting will lead to a decrease in the axial compressive strength of the pipe.
The three-dimensional finite element model is used to quantitatively calculate the axial compressive strength of reinforced and unreinforced pipe fittings. It is concluded that the axial compressive strength of reinforced pipe fittings is significantly higher than that of unreinforced pipe fittings.
Space carrier thrust bracket refers to the main force-bearing structure on the carrier that transmits the large thrust generated by the engine from one structure to another. It is generally composed of stainless steel pipe fittings, stainless steel joints, end frames and end plates.
Stainless steel pipe fittings are the main load-bearing components of the thrust bracket. They are usually made of metal materials and have a relatively large mass. Research result
