摘要
针对风力发电叶片这种典型的非回转体构件,建立其简化的物理模型和数学模型。并针对叶片主干部分的椭圆柱面,分别推导其测地线和非测地线的微分方程式。在确定封头处缠绕线型时借鉴主干部分纤维缠绕的测地线、非测地线方程,在X、Y两个方向上引入比例系数,两者结合产生缠绕线型。在封头两个平面的交界处,实现纤维由正向缠绕角到反向缠绕角的变化。最后,通过仿真和实验证明了该缠绕设计的可行性。
Using the blade of wind-driven generator, a typical non- axisymmetrical component as the investigated subject, the simplified physical and mathematical model are constructed. For the elliptic cylindrical surface which is the trunk of the blade, the geodesic and non-geodesic differential equations are deduced. In the process of the pattern design for the end, the pattern of the trunk is referenced and proportion factors of X and Y direction are introduced. The region in which the winding angle changes from positive to negative is located at the edge of two planes. At last, the feasibility of the filament winding design is proved by simulation and experiment.
