摘要
介绍了惯性释放理论以及基于CFD/CSD耦合的静气动弹性计算方法,比较了静气动弹性计算中的三种系统载荷平衡方法。三种方法的计算结果分析表明,在气动弹性计算中应用惯性释放方法能够降低施加模型约束的难度,提高模型描述的准确性及仿真计算精度。
Inertia relief theory and static aeroelastic method based on CFD/CSD are introduced in this paper. Three force equilibrium methods of static aeroelasticity are compared with. By comparing with the computational procedures and results of the three methods, it was found that applying inertia relief method in static aeroelastic method can simplify the model constraints, make the model more vivid, and enhance the simulation precision remarkably.
