| titleOfInvention | A method for predicting the ultimate load of vanadium-added steel cylinder joints considering the influence of warm coils |
| abstract | The invention discloses a method for predicting the ultimate load of a vanadium-added steel cylinder section considering the influence of warm coils. In this method, the tensile test is used to obtain the yield strength and tensile strength of vanadium-added steel with different pre-plastic deformation amounts at different service temperatures; based on the test data, the neural network technology is used to obtain the strength prediction model of vanadium-added steel; the finite element method is adopted. The residual plastic strain distribution of the barrel section after warm coil forming is predicted; then it is input into the strength prediction model to obtain the material strength distribution in the barrel section; finally, the plastic limit analysis technology is used to predict the ultimate load of the barrel section. This method has the advantages of strong operability, low cost and strong generalization ability. Through a small number of experiments, the influence of the warm coil forming process on the ultimate load of the cylinder section can be considered, and the cylinder section can be more reasonably predicted at different service temperatures. The ultimate load and material strength distribution also provide a scientific method for the optimization of the warm coil forming process parameters and the precise control of the service performance of the tube section. |
