Embodiment Construction

[0033] The present invention will be further described below in conjunction with accompanying drawing:

[0034] Such as figure 1 As shown, it is the articulated structure of the present invention, the main components include spare shock absorber 3, rotating arm 8, hinged support 6, workshop shock absorber 2 and shock absorber 7; hinged support 6 is installed on two adjacent In the section car 1, on the left side of the bottom of the front car end, the shock absorber 7 is installed on the right side of the bottom of the rear car end; Installed on the hinged support 6, so that the two ends of the rotating arm 8 can rotate horizontally around the vertical pin shaft 9; the rear end of the spare shock absorber 3 is connected with the left end of the rotating arm 8, and the rear end is installed on the front compartment 1; the workshop The front end of the shock absorber 2 is connected to the right end of the rotating arm 8, and the rear end of the workshop shock absorber 2 is inst...

Abstract

The invention discloses a hinged vibration damping method and device for actively controlling the car end of an empty rail train, comprising a workshop damper and a spare damper arranged in the hinged structure, and the workshop damper is horizontally and obliquely arranged at the corresponding Between two adjacent carriages is the only connecting piece connecting two adjacent carriages in the hinged structure; electromagnetic proportional overflow valve 1 and pressure sensor 1 are installed on the shock absorber in the workshop, and electromagnetic proportional overflow valve 1 is controlled by the control system control. The present invention has the advantages that: during the running of the train, no matter what working condition it is in, the shock absorber in the articulated structure can provide the most suitable vibration damping and damping parameters for the working condition, so that when the carriage encounters transverse and longitudinal When the acceleration amplitude increases sharply, it is always in the best mutual coordination state, and at the same time, it can effectively suppress high-speed vibration and excitation; when the workshop shock absorber fails, the longitudinal shock absorber can promptly undertake the vibration reduction mission of the hinged structure.

Description

technical field [0001] The invention relates to a vehicle-end connection vibration-damping device, and specifically designs a hinged vibration-damping method and device for actively controlling the vehicle end of an empty rail train, belonging to the technical field of rail transit. Background technique [0002] Urban aerial rail trains (or suspended rail trains) are attracting more and more attention from some cities due to their advantages such as small land occupation, small investment, fast construction, flexible route selection, and indisputable ground road resources, and will become future cities. A very important part of the transportation system. [0003] The longitudinal and lateral control of the aerial rail train operation is completely dependent on the aerial track suspended from its upper part, because the lower part of the carriage is suspended in the air without support and cannot obtain longitudinal and lateral control from the lower part. The traction conne...
