摘要
本文建立了预报两栖车辆水上行驶阻力的物理模型和数学模型,运用非结构化网格、两方程k-ε湍流模型及有限容积法求解其速度场和压力场,预测了给定工况下的车辆航驶阻力,并进行了流场的可视化分析。结果表明:运用数值方法预测阻力,为两栖车辆减阻提速的研究提供了有利的技术支持。
Both physical and mathematical models are presented for predicting the running resistance of the amphibious caterpillar vehicle. By using the non-structured mesh, k-ε turbulent model and finite volume method to calculate the flow field and pressure fielf, the prediction is done to the running resistance under given conditons. Visual analysis is also done to the flow field. The result shows the numerical simulation for resistance prediction provides an effetive support to the study on optimizing the geometrical characteristics of amphibious vehicle.
