Aiming at the working condition and object of the 9gscc - 1 . 4 sunken - plantharvesting equipment , resistances of ship body and cutting fram were analyzedby means of theory of hydromechanics and traction force of the chain - type convegor were done also by means ofcalculation of tension . power equation of the equipment , which relates to the implement ' s forward speed vm , chain - type convegor ' s linear velocity vs and cutting frame ' s angle of dip , was attained . this paper established a mathematical model for power consumption as objective function , based on thefundamental , structural dimensionof the equipment 本文根据9gscc - 1 . 4型水草收割机的工作原理及其主要结构尺寸,针对收割机的工作条件和工作对象的特性,应用流体力学理论分析计算船体及切割捡拾架的工作阻力,并用逐点张力法计算输送链的牵引力,得出整机消耗功率与机组工作速度vm 、输送链线速度vs及切割架入水角之间的关系式。
