摘　　要：为设计及验证两栖装甲突击车大风浪条件下的火控算法,需要开发其实时仿真平台。传统单刚体车辆动力学模型无法反映车体-炮塔-炮管间复杂的动力学耦合关系,不适合于高动态特性的火控仿真。使用twist-wrench方法建立了车辆的多刚体动力学模型,根据车体与视景中生成的海浪之间的运动关系计算浮力和水动力,水动力系数则事先通过计算流体力学方法得出。以一种滑模控制器为例验证了此系统作为火控算法开发及验证平台的有效性。In order to design and verify the fire control system(FCS)algorithm of amphibious assault vehicle under heavy wind and wave conditions,a real-time simulation platform is developed.The traditional single rigid body dynamic model can't describe the body-turret-barrel dynamic coupling relationship and it is not suitable for FCS simulation with high dynamic characteristics.Twist-wrench method is used to establish the multiple rigid body dynamic model of vehicle,the buoyancy and the hydrodynamic calculation is carried out according to the body and the moving relationship between visual generated waves,and the hydrodynamic coefficient is obtained by the computational fluid dynamic method.The example of a sliding mode controller verifies the effectiveness of the FCS algorithm development and verify platform.
