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。
A mathematical model for estimating the hydrostatic resistance of crawler amphibious armored vehicles is proposed. The resistance of the amphibious vehicle can be predicted at the design stage when the main parameters of the amphibious armored vehicle are known. The resistance of a certain amphibious vehicle is calculated. The hydrostatic resistance of amphibious vehicles is divided into two parts: the frictional resistance Rf and the residual resistance Rr. The results of the example are compared with the actual vehicle resistance test results. The results show that the error is small in the common speed range of the vehicle. As the speed increases, the friction resistance component of the total resistance gradually decreases while the remaining resistance component gradually increases.
