Description

Гидропневмовиброизолятор относится к области машиностроения, в частности к гидравлическим виброопорам, применяемым для демпфирования вибраций, создаваемых работающими силовыми агрегатами транспортных средств и стационарных энергетических установок.Hydropneumatic vibration isolator belongs to the field of mechanical engineering, in particular to hydraulic vibration mounts used for damping vibrations created by working power units of vehicles and stationary power plants.

Известна гидравлическая виброопора (патент RU 135380, F16F 13/10, F16F 5/00, F16F 9/10, опубл. 10.12.2013, Бюл. №34), состоящая из корпуса, заполненных демпфирующей жидкостью рабочей и компенсационной камер, разделенных металлической перегородкой с дроссельными каналами, сообщающими указанные камеры. Рабочая камера ограничена верхней опорной плитой и эластичной обечайкой, выполненной в виде тонкостенной резинокордной оболочки. Компенсационная камера ограничена мембраной. Дополнительный резинометаллический амортизатор состоит из резинового массива, ограниченного верхней и нижней опорными плитами. Оба амортизатора установлены и закреплены параллельно друг другу между общими для обоих амортизаторов верхней и нижней опорными плитами.Known hydraulic vibration mount (patent RU 135380, F16F 13/10, F16F 5/00, F16F 9/10, publ. 10.12.2013, Bull. No. 34), consisting of a housing filled with a damping fluid working and compensation chambers separated by a metal partition with throttle channels communicating these cameras. The working chamber is limited by an upper base plate and an elastic shell made in the form of a thin-walled rubber-cord shell. The compensation chamber is limited by a membrane. An additional rubber-metal shock absorber consists of a rubber array bounded by upper and lower support plates. Both shock absorbers are mounted and fixed parallel to each other between the upper and lower support plates common to both shock absorbers.

Недостатком известной гидравлической виброопоры является ее низкая эффективность при работе на различных частотах возмущающего воздействия, обусловленная отсутствием возможности проводить настройку колебательной системы для учета изменения частоты возмущающего воздействия.A disadvantage of the known hydraulic vibration mounts is its low efficiency when operating at different frequencies of the disturbing effect, due to the lack of the ability to adjust the oscillatory system to account for changes in the frequency of the disturbing effect.

Техническим результатом заявленного гидропневмовиброизолятора является повышение эффективности его работы на различных частотах возмущающего воздействия.The technical result of the claimed hydropneumatic vibration isolator is to increase the efficiency of its work at various frequencies of disturbing effects.

Технический результат достигается тем, что металлическая перегородка заменена гидравлическим инерционным трансформатором с переменной приведенной массой.The technical result is achieved by the fact that the metal partition is replaced by a hydraulic inertial transformer with a variable reduced mass.

Сущность заявляемого гидропневмовиброизолятора с переменной приведенной массой в инерционном преобразователе движения поясняется следующими чертежами:The essence of the inventive hydropneumatic vibration isolator with variable reduced mass in the inertial motion converter is illustrated by the following drawings:

фиг. 1 - гидропневмовиброизолятор вид общий;FIG. 1 - hydro-pneumatic vibration isolator general view;

фиг. 2 - принципиальная схема дискретного перекрытия дроссельных каналов.FIG. 2 is a schematic diagram of a discrete throttle channel overlap.

Гидропневмовиброизолятор состоит из корпуса 1 (фиг. 1) с полостью 2, заполненной газом под давлением Р0, рабочей камерой 3 и компенсационной камерой 4, заполненных демпфирующей жидкостью, разделенных гидравлическим инерционным трансформатором с переменной приведенной массой (ГИТ). Гидравлическим инерционный трансформатор с переменной приведенной массой состоит из корпуса 5 (фиг. 2) с дроссельными каналами 6 (инерционными трубками) и фигурного подвижного сектора 7, поворачиваемого микроэлектродвигателем 8. Рабочая камера 3 ограничена верхней опорной плитой 9 и эластичной обечайкой 10, выполненной в виде тонкостенной резинокордной оболочки. Компенсационная камера 4 отделена мембраной 11 от полости с газом под давлением P0.Hydropneumatic vibration isolator consists of a housing 1 (Fig. 1) with a cavity 2 filled with gas under pressure P 0 , a working chamber 3 and a compensation chamber 4 filled with damping fluid, separated by a hydraulic inertial transformer with a variable reduced mass (GIT). Hydraulic inertial transformer with variable reduced mass consists of a housing 5 (Fig. 2) with throttle channels 6 (inertial tubes) and a curly movable sector 7, rotated by a microelectric motor 8. The working chamber 3 is limited to the upper base plate 9 and an elastic shell 10 made in the form thin-walled rubber-cord shell. The compensation chamber 4 is separated by a membrane 11 from the cavity with gas under pressure P 0 .

Гидропневмовиброизолятор работает следующим образом. При воздействии на верхнюю опорную плиту 9 статической нагрузки от виброактивного силового агрегата (на чертеже не показан) эластичная обечайка 10 деформируется. При этом объем рабочей камеры 3 уменьшается, что вызывает выталкивание рабочей жидкости из рабочей камеры 3 через дроссельные каналы 6 в корпусе ГИТ 5 в компенсационную камеру 4. Вследствие чего резиновая мембрана 11 деформируется и объем компенсационной камеры 4 увеличивается на величину уменьшения объема рабочей камеры 3. Фигурный подвижный сектор 7, поворачиваемый электродвигателем 8, обеспечивает дискретное перекрытие дроссельных каналов 6, что позволяет проводить настройку колебательной системы на минимум коэффициента передачи в зависимости от частоты возмущающего воздействия.Hydropneumatic vibration isolator works as follows. When exposed to the upper base plate 9 of a static load from a vibroactive power unit (not shown), the elastic shell 10 is deformed. In this case, the volume of the working chamber 3 decreases, which causes the working fluid to be pushed out of the working chamber 3 through the throttle channels 6 in the GIT housing 5 into the compensation chamber 4. As a result, the rubber membrane 11 is deformed and the volume of the compensation chamber 4 increases by the amount of reduction in the volume of the working chamber 3. Figured movable sector 7, rotated by an electric motor 8, provides a discrete overlap of the throttle channels 6, which allows tuning of the oscillatory system to a minimum transmission coefficient depending imosti frequency disturbance.

Заявленный гидропневмовиброизолятор, оснащенный гидравлическим инерционным трансформатором с переменной приведенной массой, позволяет повысить эффективность демпфирования возмущающего воздействия путем настройки колебательной системы на минимум коэффициента передачи в зависимости от частоты возмущающего воздействия.The claimed hydropneumatic vibration isolator equipped with a hydraulic inertial transformer with variable reduced mass, allows to increase the efficiency of damping of the disturbing effect by tuning the oscillating system to a minimum transmission coefficient depending on the frequency of the disturbing effect.
