Bent pipe variable wall thickness design method and device based on TRESCA strength theory

The invention relates to a bent pipe variable wall thickness design method and device based on a TRESCA strength theory. The method includes: firstly, modeling the bent pipe; establishing a dimensionless pressure distribution model; and solving an undetermined coefficient of the dimensionless pressure distribution model force according to numerical simulation, substituting the solved undeterminedcoefficient into the circumferential distribution stress formula and the axial distribution stress to judge the main stress, and finally establishing a variable-wall-thickness bent pipe wall thicknessmathematical model according to the circumferential distribution stress distribution formula or the axial distribution stress distribution formula. By means of the bent pipe variable wall thickness design method and device based on the TRESCA strength theory, the variable wall thickness bent pipe can be designed, and the safety of the bent pipe in the pipeline conveying process is checked. 本申请涉及一种基于TRESCA强度理论的弯管变壁厚设计方法和装置
