摘要
基于摩擦阻力经验公式计算板体与附体的粘性阻力,其中,湿面积采用了梯形面积计算的方法与辛卜生二次抛物线面积计算方法,2种方法计算结果一致。又由于总阻力等于粘性阻力与兴波阻力之和(粘性阻力由摩擦阻力与形状阻力构成),将水池试验测得的总阻力减去粘性阻力即得到兴波阻力的大小,进一步计算出不同船速下各种阻力成分的比例。
This paper calculated viscous-resistance of board and subordinate based on friction-resistance formula, thereinto, dank area used the two kinds of calculating method of trapezia and simpson square-arabola, and their calculating results was accordant. Since the viscous-resistance was consist of friction-resistance and shape-resistance, the total resistance measured in experiment minus the viscous-resistance was wave-resistance and then calculated the proportion of viscous resistances in several different velocity of board, it will provide some important warrant for sailboard athletes control Key words：
