摘 要:在对模型车试验的基础上,提出了步行轮式气垫车系统需求功率匹配模型和最佳匹配关系的概念。通过速度品质系数和载荷品质系数将垫升和驱动需求功率比与运输效率建立了联系,并且对最佳需求比进行了初略估计。结果表明在一定的车速、土壤条件和载荷下,步行轮存在着一个合适的入土深度,此时总需求功率最小,而此时的功率匹配和载荷匹配关系则是最佳的。This study put forward a model of systematic needed power matching and a concept of optimum matching relation about air cushion vehicle of walking wheel type. It also built up the relations between the hovering and driving needed power ratios and transport efficiency by the quality coefficients of velocity and weight, and estimated the value of optimum needed power ratio. The dynamic digital simulation and related test were done to study the relations of the optimum needed power matching between the hovering system and driving system. The results indicate that the walking wheel exists a suitable cutting depth with the lowest total needed power, the best power matching and the weight distribution under certain velocity of vehicle, soil and load.
