Stability Analysis of Amphibious Armored Vehicles Entering the Water from Land

摘要:

对两栖装甲车辆水动力学模型的构建以及基于水上航行耐波稳定性的横摇运动进行了探索。首先建立了两栖装甲车辆由陆入水的动力学模型,并进行了仿真分析；而后将模型试验与融入遗传算法的系统辨识思想相结合,构建了对于两栖装甲车辆摇荡运动的辨别模型；最后通过对车辆在水上的横摇运动试验设计及侧体方案布置,对辨别模型的应用效果进行了验证。通过研究发现,水动力学模型能够对两栖装甲车辆由陆入水时的车体稳定性情况进行准确描述,基于遗传算法的系统辨识方法能够分段辨识两栖装甲车辆的横摇运动,为车辆水上航行稳定性的研究提供了借鉴。

Abstract:

The integration of the amphibious armored vehicle hydrodynamic model and the roll motion based on the stability of sea navigation wave resistance were explored. First, the dynamic model of amphibious armored vehicles entering the water from land was established, and simulation analysis was carried out. Then, the model test was combined with the idea of ??integrated genetic algorithm system identification, and the identification model for the amphibious armored vehicle swaying motion was identified. The experimental design of the rolling motion of the vehicle on the water and the layout of the side body scheme verified the application effect of the discrimination model. Through research, it is found that the hydrodynamic model can accurately describe the stability of the amphibious armored vehicle when it enters the water from the land. The system identification method based on genetic algorithm can distinguish the rolling motion of the amphibious armored vehicle, which is the stability of the vehicle on water "S research provides direction.
