Description
Изобретение относитс к судостроению, в частности к устройствам дл управлени многовальной судовой энергетической установкой .FIELD OF THE INVENTION The invention relates to shipbuilding, in particular, to devices for controlling a multi-shaft ship power plant.
Цель изобретени - снижение вибрации корпуса судна.The purpose of the invention is to reduce the vibration of the hull.
На чертеже схематично изображено предлагаемое устройство, общий вид.The drawing schematically shows the proposed device, a General view.
Система содержит датчик 1 вибрации (на чертеже показан один датчик), выход которого св зан с входом фильтра 2 низких частот. Выход фильтра 2 св зан с входом дифференцирующего усилител 3, выход которого св зан с входом блока 4 сравнени . Выход блока 4 сравнени св зан с входом блока 5 согласовани , выходы которого св заны с регул тором 6 частоты вращени двигател 7 и с механизмом 8 изменени гиага гребного винта 9.The system contains a vibration sensor 1 (one sensor is shown in the drawing), the output of which is connected to the input of a low-pass filter 2. The output of the filter 2 is connected to the input of the differentiating amplifier 3, the output of which is connected to the input of the comparison unit 4. The output of the comparison unit 4 is connected to the input of the matching unit 5, the outputs of which are connected to the engine speed regulator 6 of the engine 7 and the mechanism 8 for changing the propeller shaft 9.
Устройство работает следующим образом .The device works as follows.
Датчик 1 измер ет вибрацию некоторых характерных точек корпуса судна. ОгибаюSensor 1 measures the vibration of some characteristic points of the hull. Ogiba
ща этого сигнала, выделенна фильтром 2 низких частот, поступает через дифференцирующий усилитель 3 на вход блока 4 сравнени . Логическа схема блока 4 сравнени вырабатывает управл ющий сигнал, который в случае убывани амплитуды огибающей вибрации, измер емой датчиком 1, обеспечивает продолжение изменени фазового угла гребных валов в том же направлении , в противном случае направление изменени фазового угла гребных валов реверсируетс .This signal, separated by a low-pass filter 2, is fed through differentiating amplifier 3 to the input of comparator 4. The logic circuit of the comparison unit 4 generates a control signal which, in case of a decrease in the amplitude of the vibration envelope measured by the sensor 1, continues the change in the phase angle of the propeller shafts in the same direction, otherwise the direction of change in the phase angle of the propeller shafts is reversed.
Управл ющий сигнал блока 4 сравнени поступает через блок 5 согласовани с регул тором 6 частоты вращени , которым охвачен двигатель 7, на механизм 8 изменени шага гребного винта 9, либо на механизм перемещени топливной рейки двигател 7. При этом за счет блока 5 согласовани с регул тором 6 происходит изменение фазы вращени одного из гребных валов, при неизменной (после отработки управл ющего воздействи ) частоте вращени .The control signal of the comparison unit 4 is fed through the matching unit 5 with the rotation speed controller 6, which covers the engine 7, to the mechanism 8 for changing the pitch of the propeller 9, or to the displacement mechanism of the fuel rail of the engine 7. Herewith due to the adjusting unit 5 The torus 6 changes the phase of rotation of one of the propeller shafts, at a constant (after the control action has been developed) rotation frequency.
