Development and Application of Simulation Platform for Aquatic Movement of an Amphibious Armored Vehicle
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.
