GFRP材料对微水头水车叶片结构性能的影响
Effect of GFRP material on structural performance of micro head waterwheel blades
摘要
Abstract
According to the theory of unidirectional fluid structure coupling,the fluid pressure data,derived from simulations of the fluid pressure experienced by the blade at different rotation angles,were utilized as the boundary condition for structural analysis and subsequently incorporated into the fi-nite element analysis model for further examination.The structural design of waterwheel blades was conducted using epoxy S-glass fiber and epoxy E-glass fiber materials.The influence of different layer laying angles in the composite materials on the mechanical properties of waterwheels was explored,ai-ming to determine the optimal layering scheme.Furthermore,the structural analysis results of the com-posite blades were compared with those of blades with a solid structure.The results indicate that the ap-plication of epoxy E-glass fiber material,combined with a layer stacking scheme with a layer laying an-gle θ=15°,has the most significant improvement in the structural performance of micro head water-wheel blades.In comparison to solid steel blades under the same operating conditions,the maximum deformation of composite blades is reduced by 53.4％,thereby effectively alleviating the phenomenon of stress concentration.Additionally,the mass of composite blades is greatly reduced,achieving a weight reduction effect of 80.7％.These results provide a theoretical basis for the safe and efficient de-sign of micro head waterwheel blades.关键词
