为实现对复合材料螺旋桨强度进行准确的评估,本文基于Hashin强度准则对特定铺层的螺旋桨在设计工况水动力载荷下进行强度评估;鉴于模拟螺旋桨所受水动力载荷具有很大的局限性,开展等效集中力研究;静强度试验表明,有限元计算结果与试验结果吻合较好,各测点处应变均呈线性增长,有效佐证了强度评估方法的可靠性。
In order to realize an accurate assessment of the strength of the propeller, firstly, the strength of the assessment about propeller of specific overlay under hydrodynamic loads was conducted,which was based on the Hashin strength criterion.Then, given that the simulation of propeller under hydrodynamic load was of great limitation, the equivalent concentrated force was studied. Lastly, the static strength experiment shows the finite element calculation results have good agreement with the test results. In addition, the strain of every measuring point increased linearlywhich effectively supported the reliability of the strength.
