稳定状态下锥形伞结构分析

通过合理简化和假设确定轴对称锥形降落伞模型，建立了充满稳定状态下锥形伞受力平衡微分方程，然后根据空间几何关系和弹性力学，补充约束方程，通过数值方法求解方程，最终得到伞绳和伞衣的形状和应力。编成非线性迭代程序对锥形伞进行验证。算例表明，该模型可以用于锥形伞结构的初步分析和设计。

Analysis of Steady-state Conical Parachute Structure

A symmetrical conical parachute model is confirmed through proper simplification and assumption. The differential equations of conical steady-state parachute structure are established. The equations are solved by numerical methods considering the boundary conditions through space geometrical relations and elastic mechanics. At last, parachute shape and stress are obtained. According to it, one conical parachute is tested by a nonlinear iterative program. Examples indicate that this model is suitable for analysis and general design of steady-state parachute.
