The invention provides a rigid-flexible coupling missile and rocket dynamics modeling method composed of a parafoil and a missile and rocket, the parafoil and the traditional missile and rocket are combined, a parafoil-missile system composed of the parafoil and the missile is provided, and the controllable parafoil is additionally arranged on the missile to serve as a control surface to achieve the scheme that the missile turns agilely. A rigid-flexible coupling parachute-missile system composed of a parafoil and a missile is subjected to dynamic modeling, and the maneuverability increment of the missile and rocket type aircraft can be achieved; meanwhile, a hinge point C is equivalent to a mass point, a parafoil and a missile are equivalent to rigid bodies, and a parachute cord is equivalent to a flexible spring-damping model, so that a 15-degree-of-freedom motion model of the parachute-missile system is formed, and the 15-degree-of-freedom motion model can be used for nonlinear dynamic characteristic research and has the characteristics of high precision, high speed and high dynamic motion; that is to say, the method can provide theoretical support for the parachute missile system to break through constraints of conditions such as geometric shapes and aerodynamic layouts, so that the high-strength requirement of modern military fighting is better met.

    本发明提供一种由翼伞和弹箭构成的刚柔耦合弹箭动力学建模方法,将翼伞与传统弹箭相结合,提出一种由翼伞‑导弹组成的伞弹系统,在导弹上加装可控翼伞作为控制面实现弹敏捷转弯的方案,并对由翼伞和导弹构成的刚柔耦合伞弹系统进行动力学建模,能够实现弹箭类飞行器机动能力增量;同时,本发明将铰接点C等效为质点,翼伞和导弹等效为刚体,伞绳等效为柔性的弹簧‑阻尼模型,由此共同构成了伞弹系统15自由度运动模型,可用于非线性动力学特性研究,具有高精度、高速、高动态运动的特点;也就是说,本发明能够为伞弹系统突破几何外形、气动布局等条件的约束提供理论支撑,从而更好的满足现代军事斗争的高强度需求。
