A test device for simulating train body deformation and ramp inclination

Abstract

The invention discloses a test device for simulating the deformation of a train body and the inclination of a ramp, comprising a base assembly and a door frame deformation system, the door frame deformation system is fixedly installed on the base assembly, and the door frame deformation system includes a fixing frame, A door frame assembly, a first three-way loading assembly, a second three-way loading assembly, a third three-way loading assembly, a fixed assembly, and a moving assembly. The base assembly of the present invention adopts the method of combining the loading electric cylinder and the balance cylinder, and realizes the smooth driving of the platform through the universal joint, simulating the situation that the ramp is inclined at a large angle; at the same time, the door frame deformation system can be integrally installed on the platform of the base assembly to simulate The function test of the door system under the combined influence of vehicle body deformation and slope inclination; at the same time, the deformable door frame assembly is used to realize the flexible deformation of the door frame with a small electric cylinder driving force, and at the same time, it can also ensure that the door frame has sufficient rigidity.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a test device for simulating the deformation of a train body and the inclination of a ramp. Background technique [0002] At present, the type test of rail transit door system is carried out by installing the door system on the tooling bench with the theoretical interface size. However, there are uncertain factors such as overload and the slope of the driving track during official operation. Deviation will occur, and the door system will have forced displacement, which may cause large running resistance. If the resistance is too large, the door will not be able to open and close normally. When the running track has a slope, the gravitational moment of the center of gravity of the door leaf changes, and the force on the drive mechanism of the door system will also change, which may also lead to failure of the door opening and closing. [0003] It can be seen that unex...
