A digital reactor simulation analysis method for flow-induced vibration of large pressurized water reactor core structure |
| abstract |
The invention discloses a digital reactor simulation analysis method for flow-induced vibration of a large-scale pressurized water reactor core structure. The method includes the following steps: S1: respectively use the flow in the lower head of the reactor pressure vessel, the core and the fuel assembly. Field as the object, perform data-driven analysis and simulation of the flow characteristics and fluid mechanics of the flow field in the reactor; S2: According to the results of the analysis and simulation output in step S1, establish the fuel rods at the element level, the fuel assemblies at the assembly level and the full core fuel. Structural dynamics model of the finite element discrete equation of the component under the action of fluid excitation, analyze the governing equation solving strategy of multiple nonlinear factors and multiple spatiotemporal scale coupling of the core structure; S3: solve the mechanical behavior of the core structure according to the governing equation, and solve the problem Sensitivity analysis and uncertainty quantification are carried out on the input-output sample data of the core structure to complete the analysis of the flow-induced vibration behavior of the core structure at multiple spatiotemporal scales. |
