【Abstract】 Calculation and theoretical analysis are presented concerning bending pipe liquid stress. The structural research and stress analysis method of bending pipe are discussed. Final stress distribution of bending pipe affected by the fluid are obtained, through finite differential method to achieve bending pipe design and manufacture destination. The calculation program is compiled in finite element software—ANSYS, and the procedure is compact and fast, so it can satisfy the requirement of complex engineering design. It is show that the research method of this paper is feasible and effective. At the same time, the influence of bending pipe and fluid parameter to the stress are discussed, some valuable results are presented.更多还原
