(54) УСТРОЙСТВО ДЛЯ АЭРОГИДРОДИНАМИЧЕСКИХ ИСПЫТАНИЙ МОДЕЛЕЙ В ОПЫТОВОМ БАССЕЙНЕ(54) DEVICE FOR AIR HYDRODYNAMIC TESTS OF MODELS IN THE EXPERIENCE BASIN
II
Изобретение относитс к оборудованию и устройствам опытовых бассей-нов дл проведени аэрогидродинамических испытаний, и в частности к устройству дл буксировкимоделей в опытовых бассейнах.The invention relates to equipment and devices for test tanks for aero-hydrodynamic tests, and in particular to a device for towing models in test pools.
Известны устройства дл буксировки моделей в опытовых бассейнах, содержащие буксировочную тележку с двигателем и разгонное приспособление в виде силового пневмоцилиндра 1.Known devices for towing models in a pilot basin, containing a towing car with the engine and the accelerating device in the form of a power pneumatic cylinder 1.
Однако разгонное приспособление в виде одного силового пневмоцилиндра не позвол ет обеспечить разгонный участок сравнительно больших размеров, с заданием на нем различных скоростей разгона.However, an acceleration device in the form of a single power pneumatic cylinder does not allow for an acceleration section of relatively large dimensions, with assignment of different acceleration speeds on it.
Цель изобретени - обеспечение управл емого по ускорению участка разгона буксировочной тележки и увеличени участка установившегос движени модели.The purpose of the invention is to provide an accelerated acceleration section of the towing carriage and an increase in the steady-state portion of the model.
Поставленна цель достигаетс тем, что устройство снабжено прикрепленной к штоку пневмоцилиндра разгонной тележкой, содержаш ,ей ходовые колеса, направл юш,ие ролики и демпферное устройство, взаимодействующее с буксировочной тележкой.The goal is achieved by the fact that the device is equipped with an acceleration trolley attached to the rod of the pneumatic cylinder, which contains the driving wheels, guides, rollers and a damper device that interacts with the towing trolley.
На чертеже схематически изображено устройство , общий вид.The drawing shows schematically the device, a general view.
Устройство состоит из пневмоцилиндра 1, имеющего длину рабочего хода поршн со штоком 2, необходимую дл задаваемого участка разгона. Шток св зан с разгонной тележкой 3, котора имеет ходовые колеса 4, направл ющие ролики 5, демпферное 5 устройство 6 в ее передней части, взаимодействующее с буксировочной тележкой 7, содержащей экспериментальную установку (модель) 8, и статор линейного асинхронного двигател 9.The device consists of a pneumatic cylinder 1 having a stroke length of the piston with a rod 2, necessary for a given acceleration section. The rod is connected with the acceleration car 3, which has traveling wheels 4, guide rollers 5, damping device 5 6 in its front part, interacting with towing car 7 containing the experimental unit (model) 8, and the stator of the linear asynchronous motor 9.
ОУстройство работает следующим образом .The device works as follows.
В исходном положении перепад давлени 8 пневмоцилиндре отсутствует, разгонна тележка 3 занимает крайнее правое положение , буксировочна тележка 7 прижата к In the initial position, the pressure drop 8 to the pneumatic cylinder is absent, the acceleration car 3 takes the extreme right position, the tow car 7 is pressed to
15 демпферному устройству 6. При подаче воздуха в пневмоцилиндр происходит движение разгонной тележки и она через демпферное устройство 6 толкает буксировочную тележку 7 с ускорением, тем больщим, чем больше 2Q давление воздуха в пневмоцилиадре, которое регулируетс пневмосхемой в соответствии с необходимостью получеми .ал .пМ ускорени .15 damping device 6. When air is supplied to the pneumatic cylinder, the acceleration car travels and it pushes the towing car 7 through the damping device 6 with acceleration, the greater the higher the 2Q air pressure in the pneumatic cylinder, which is regulated by the pneumatic circuit in accordance with the need to obtain the air. speed up
Предлагаемое устройство позвол ет получить управл емый по величине участок разгона и увеличить участок режима установившегос движени , расшир тем самым возможности проведени испытаний в широком диапазоне ускорений и увеличива достоверность регистрируемой информации за счет увеличени времени съема этой информации.The proposed device makes it possible to obtain a controllable acceleration segment and increase the portion of the steady-state regime, thereby expanding the possibility of testing in a wide range of accelerations and increasing the reliability of the recorded information by increasing the acquisition time of this information.
