此文作为一个初步探索,主要是对一种桨叶根部段进行强度分析。通过有限元建模分析、网格划分、绘制应力和变形云图及试验结果对比,首次对这种桨叶根部段进行强度评估。数值计算结果与试验结果对比分析显示,数值计算结果与试验结果基本吻合,数值计算结果真实有效,同时初步认定该结构具有较好的静强度。
As a preliminary exploration, this paper mainly analyzes the strength of a blade root section. Through the finite element modeling analysis, meshing, drawing stress and deformation cloud chart and the comparison of the test results, the strength evaluation of the root section of the blade was conducted for the first time. Comparing the numerical results with the experimental results, the numerical results are in good agreement with the experimental ones, and the numerical results are true and valid. Meanwhile, the structure is found to have good static strength.
