Изобретение касаетс устройств дл испытани железнод9рожных транспортных средств на физических модел х .The invention relates to devices for testing railway vehicles on physical models.
Известна установка дл исследовани железнодорожных транспортных средств на физических модел х, содержаща станину, несущую смонтированные с возможностью вращени в вертикальной плоскости опорные катки с беговой дорожкой, воспроизвод щей профиль головки рельса, оси вращени которых кинематически св заны с маховиком , имитирующим массу поезда L1J.A known installation for the study of railway vehicles on physical models, comprising a frame supporting vertical rollers mounted for rotation in a vertical plane with a treadmill reproducing the railhead profile, the rotation axes of which are kinematically associated with a train mass L1J.
Установка не позвол ет имитировать дв,ижемие железнодорожных транспортных средств на уклонах и не учитывает сопротивление воздушной среды и, таким образом, не обеспечивает эксплуатационных условий.The installation does not allow to imitate dv, ijemie rail vehicles on slopes and does not take into account the resistance of the air environment and, thus, does not provide operational conditions.
Цель насто щего изобретени расишрение функциональных вoз лoжнocтей .The purpose of the present invention is the resolution of functional constraints.
Поставленна цель достигаетс теМу что установка снабжена упруго подвешенной к станине фрикционной колодкой, взаимодействующей с опорным катком, а на маховике, имитирующем массу поезда, смонтированы с переменным углом наклона лопасти дл The goal is achieved by the fact that the installation is equipped with a friction pad, which is elastically suspended from the frame, interacting with the support roller, and on the flywheel simulating the mass of the train are mounted with a variable angle of inclination of the blade for
взаимодействи с набегающим воздушным потоком.interaction with oncoming air flow.
На фиг. 1 изображена установка, вид сверху; на фиг. 2 - то же, вид спереди.FIG. 1 shows the installation, top view; in fig. 2 - the same, front view.
Установка содержит основание 1, на котором с возможностью вращени в вертикальной плоскости смонтированы опорные катки 2 с беговой дорож0 кой, повтор квдей профиль головки рельса. Оси 3 опорных катков 2 кинематически св заны с маховиком 4, имитирукидим массу поезда. К маховику 4 закреплены лопасти 5 с перемен5 ным углом наклона, которые в процессе работы установки взаимодействуют с набегающим воздушным потоком.The installation comprises a base 1, on which support rollers 2 with a running track are mounted with the possibility of rotation in a vertical plane, repeating the rail head profile. The axles 3 of the road wheels 2 are kinematically associated with the flywheel 4, imitating the mass of the train. The blades 5 are fixed to the flywheel 4 with a variable angle of inclination, which, in the process of operating the installation, interact with the incoming air flow.
На станине 1 упруго подвешена фрикционна колодка 6, взаимодействующа с опорным катком 2.On the base 1, a friction block 6 is resiliently suspended, interacting with the support roller 2.

Установка работает следующим образом .The installation works as follows.
Дл моделировани ветровой нагруэки лопасти 5 поворачивают вокругTo simulate the wind load, the blades 5 rotate around
своей оси и фиксируют в нужном положении . При вращении они создают рал счетное сопротивление, которое соответствует ветровой нагрузке дл данного железнодорожного транспортногоits axis and fixed in the desired position. During rotation, they create a ral countable resistance that corresponds to the wind load for a given railway transport
