摘要
Abstract
To study the effect of grille components on the efficiency of waterjet propulsion ships,we use the numeri-cal calculation method of fluid-structure interaction to systematically calculate the force and strength characteristics of the grid surface.Combined with the finite element(FEM)method and fluid-structure interaction theory and based on the STARCCM+and ABAQUS software—using the currently known design method of the grid section—the existing section form of the grid is improved,forming a new type of grid with a symmetrical section.Based on the abovementioned computational fluid dynamics and fluid-structure coupling calculation methods,the surrounding flow field,structural static strength,and structural dynamic strength are calculated and analyzed.Results show that the symmetrical grid section helps reduce the deformation and stress level of the grid.The new symmetrical profile structure has changed the overall deformation mode of the grid,but the maximum deformation position and maxi-mum stress have not obviously changed.The new grid with a symmetrical section has better static strength and dy-namic strength characteristics,and each grid bar bears the fluid load evenly.关键词
