The invention discloses a shipborne captive balloon multi-body dynamics modeling and numerical simulation method, which comprises the following steps: establishing a multi-rigid-body dynamics model of a shipborne captive balloon, programming the modeling process by using a programming language, completing secondary development modeling and simulation in multi-body dynamics calculation software, and submitting to a solver for calculation. Based on the advantage that shaft sleeve force one-class flexible connection can equivalently replace spherical hinge pair one-class rigid connection in the system, the number of constraint equations in a vehicle multi-body system kinetic equation is reduced, and then more efficient real-time simulation and control of the shipborne captive balloon are achieved.

    本发明公开了一种船载式系留气球多体动力学建模与数值仿真方法,该方法建立船载式系留气球的多刚体动力学模型,然后将建模过程用程序化语言编程并在多体动力学计算软件中完成二次开发建模及仿真,提交求解器进行计算。本发明基于轴套力一类柔性连接可以等效替换系统中球铰副一类刚性连接的优势,从而降低车辆多体系统动力学方程中约束方程的个数,进而实现船载式系留气球更加高效的实时仿真与控制。
