摘　　要：为了解决高海况条件航行时,两栖车辆水上航行安全性预测问题。基于某两栖车的实车三维几何模型,采用计算流体力学方法、重叠网格技术以及数值造波技术,建立了两栖车多体运动水上性能数值仿真模型。基于该模型,对两栖车在不同海况下动态加速动力学性能进行了数值模拟,预测和分析了动态加速过程中整车速度、纵倾、升沉运动以及耐波性能。并通过拖模试验、实车静水试验等手段,验证仿真模型的准确性。结果表明,仿真分析结果与试验结果一致性较好,该模型具有较高的仿真精度。该模型能够预测两栖车辆不同海况下动态加速动力学及耐波性能,为进一步研究两栖车辆水上航行安全性提供了有效技术途径。In order to solve the problem of safety forecast of amphibious vehicle sailing on water under high sea condition,based on the three-dimensional geometric model of an amphibious vehicle,a numerical simulation model of amphibious vehicle’s multi-body sports performance on water was established by means of computational fluid dynamics,overlapping grid technology and numerical wave generation technology.Based on this model,the dynamic acceleration dynamic performance of the amphibious vehicle under different sea conditions was numerically simulated,and the vehicle speed,pitch,heave motion and wave resistance performance during dynamic acceleration were predicted and analyzed.The accuracy of the simulation model was verified by means of towing model test and real vehicle hydrostatic test.The results show that the simulation analysis results are agree with the results of towing mode testandhydrostatic test,and the simulation accuracy of the model is high.The model can predict the dynamic acceleration dynamics and wave resistance performance of amphibious vehicles under different sea conditions,and provide an effective technical way for further research on the safety of amphibious vehicles on water navigation.
