船式车辆船体起步阻力理论及试验研究

MECHANISM AND EXPERIMENTAL RESEARCH ON STARTING RESISTANCE TO HULL OF BOAT-TYPE VEHICLE

分析了船式车辆的行驶特点及船体起步阻力的形成机理，建立了船体起步阻力的预测模型，并对此模型进行了室内土槽试验验证，结果表明，试验结果与预测计算基本吻合。

Based on the operating characteristics of boat-type vehicle,this paper analyses the for-mation mechanism of starting resistance to the hull of boat-type vehicle and demonstratedthat the soil parameters C andφ change along with the changes in the soil moisture content,and put forward the predicting model for starting resistance. At the same time,the startingresistance to the hull has been preliminarily calculated by computer and verified by the exper-iments in soil bin. The result of test has shown that the experimental values with the compu-tation values are approximate. Through these researches into the hull starting resistance andits effecting elements,further research could be carried out to explore methods for reducingthe hull starting resistance.
