| 摘 要： | 本文对Krahula,J.L.等人提出的“圣维南扭转的有限元解”作了合理的改进,使改进后的公式能很方便地编成计算程序,作复合材料旋翼桨叶的扭转刚度计算。还应用改进后的公式计算了两种型号直升机旅翼桨叶的扭转刚度,计算值和试验值有很好的一致性。

| Abstract: | The finite element solution for Saint-Venant Torsion presented by Krahula, J.L. and Lauterbach, G.F. is reasonably improved in this paper, and it is quite convenient to compile a computer program with the improved formula. The numerical results of calculating the torsional stiffness of a rotor blade cross section of two types of helicopters are thus obtained from the improved formula, and the calculating results are compared with their experimental values in good agreement. |
