| 摘 要： | 提出了一种估算履带式两栖装甲车静水阻力的数学模型,在车辆主要参数已知的情况下,可对该型两栖车进行设计阶段的阻力预测:并针对某型两栖车进行了阻力计算。将两栖车辆的静水阻力分为摩擦阻力Rf剩余阻力Rr.等两部分,把实例估算结果与实车阻力试验结果相对比,结果表明:在该车常用航速范围内,误差较小。随着航速的提高,总阻力中摩擦阻力成份逐渐减少,而剩余阻力成份逐渐增加。

| Abstract: | In this paper, proposes a mathematical model for predicting static water resistance of amphibious vehicles and calculates the resistance of certain type of amphibious vehicle. Dividing the static water resistance into friction resistance Rl and residuary resistance R2, we compare the calculating results with the real resistance. The conclusion shows that, within the speed limitation, error is minimum. With the increasing of the speed, the friction resistance decreases while residuary resistance increases. |
