Simulation Researchon Displacement Rule of Amphibious Armored Vehicles Shooting in Water

两栖战备车辆水上射击动力学模型研究,以某轮式自行火炮为例,在车辆左右完全对称、静水条件纵中面内射击等假设的基础上,对两栖武器水上射击动力学模型进行了合理简化。采用水动力无因次体系法对该自行火炮的水动力试验数据进行合理转换,近似得到轮式自行火炮的水动力参数;运用MATLAB对轮式自行火炮水上射击动力学方程进行了解算,获得了静水条件下某轮式自行火炮水上射击位移特性数值计算结果,最后对计算结果进行了评估与分析,得到了火炮的水上射击位移规律。

In case of one wheeled self-propelled artillery, under the condition of complete symmetry about the amphibious vehicle and firing in the face middle-surface of longitudinal on the still water, firstly, the paper simplified the dynamics model of amphibious weapons firing in water, carried out some reasonable transformation of one amphib- ious vehicle dynamic test data by using hydrodynamic non-dimension method and obtaining the approximate value of hydrodynamic parameters of the wheeled self-propelled artillery. Secondly, by using MATLAB to solve the dynamics equation of wheel self-propelled artillery firing in water, we obtained the calculation results of the displacement char-acteristics value when the artillery was firing in static water. Finally, by evaluating and analyzing the results, the pa- per summarized the displacement rule of the artillery firing in water.
