Claims (1)

Способ управления рабочим органом землеройно-транспортной машины, при котором измеряют текущие значения силы тяги на рабочем органе и действительной скорости движения машины, получают текущие значения тяговой мощности машины путем перемножения величин силы тяги и действительной скорости, определяют знаки приращений силы тяги и тяговой мощности и в зависимости от их соотношений формируют управляющий сигнал на заглубление - выглубление рабочего органа землеройно-транспортной машины, отличающийся тем, что одновременно с измерением силы тяги на рабочем органе и действительной скорости движения машины измеряют текущие значения угловой скорости вращения вала двигателя и крутящего момента на нем, получают текущие значения развиваемой двигателем мощности путем перемножения величин угловой скорости и крутящего момента, после чего получают текущие значения КПД машины путем деления тяговой мощности машины на величину мощности двигателя и получают текущие значения эффективной тяговой мощности машины путем перемножения величин ее тяговой мощности и КПД, а знаки приращений определяют одновременно эффективной тяговой мощности машины и ее силы тяги.The way to control the working body of the earth moving machine, in which the current values of the traction force on the working body and the actual speed of the machine are measured, the current values of the traction power of the machine are obtained by multiplying the values of the traction force and the actual speed, the signs of the increments of the traction force and traction power are determined and depending on their ratios form a control signal for deepening - deepening the working body of the earth moving machine, characterized in that at the same time as measuring forces The thrust on the working body and the actual speed of the machine measure the current values of the angular speed of rotation of the engine shaft and the torque on it, obtain the current values of the power developed by the engine by multiplying the values of the angular speed and torque, and then obtain the current values of the efficiency of the machine by dividing the traction power machines by the amount of engine power and get the current values of the effective traction power of the machine by multiplying the values of its traction power and efficiency, and the signs of increment th determine simultaneously the effective traction power of the machine and its traction.
