Problems solved by technology

This method has the following disadvantages: (1) the structure is complex, and the angle between the drawbar and the horizontal direction of the vehicle body cannot be well simulated; (2) due to the deformation of the vehicle body during the loading process, there is a risk of the loading cylinder being stuck, thereby make the loading impossible

Embodiment 1

[0029] Such as Figure 1-Figure 2 As shown, the present invention discloses a vehicle body static strength test device that simulates the impact load of a bogie. Among them, the vehicle body static strength test device includes a vertical support 1, a reaction frame 2 and a traction seat loading device 4. The vertical support 1 is used to support the vehicle body 3 to be tested, and the reverse frame is installed on the embedded track and is The ends of the vehicle body 3 are hinged.

[0030] The traction seat loading device 4 includes a support seat 401, a triangular reaction lever 402, a driving device 403, a connecting rod 404, a load sensor 405, and an analog traction seat 406.

[0031] The support base 401 is fixed on the embedded track. In order to disassemble and assemble the support base 401, in this embodiment, it is specifically disclosed that the support base 401 is fixed on the embedded track by bolts. The top end of the support base 401 is hinged to the bottom edge o...

Embodiment 2

[0039] In the second embodiment provided by the present invention, the static strength test device for simulating the impact load of the bogie in this embodiment has a similar structure to the static strength test device for simulating the impact load of the bogie in the first embodiment. I won’t repeat the similarities, and only introduce the differences.

[0040] In this embodiment, it is specifically disclosed between the support base 401 and the bottom side of the triangular reaction lever 402, between the driving end of the driving device 403 and the bottom side of the triangular reaction lever 402, the connecting rod 404 and the triangular reaction lever 402 The top ends of the traction seat 406 and the connecting rod 404 are all hinged with cylindrical pins. That is, the support base 401, the driving device 403, and the connecting rod 404 are detachably connected with the triangular reaction lever 402, and the simulating traction base 406 and the connecting rod 404 are det...

Abstract

The present invention discloses a vehicle body static strength test device for simulation of bogie impact load. The vehicle body static strength test device comprises a vertical support and a reactionframe, the vertical support is configured to support a vehicle body to be tested, and the reaction frame is installed on a pre-embedded track and is hinged with an end portion of the vehicle body; and the vehicle body static strength test device further comprises a traction seat loading device which comprises a support seat fixed on the pre-embedded track, a triangular reaction lever hinged withthe support seat, a driving device having a driving end being abutted against an end portion of a bottom side of the triangular reaction lever, a connection rod hinged with a top end of the triangularreaction lever, a load sensor installed on the connection rod and configured to detect force on the connection rod, and a simulation traction seat hinged with the connection rod and fixedly connectedwith the bottom portion of the vehicle body. The simulation traction seat is hinged with the connection rod and the connection rod is hinged with the triangular reaction lever, and therefore, a condition of an inclined angle between the traction rod and the horizontal direction of the vehicle boy can be simulated and it can be avoided that a driving device is jammed.

Description

Technical field [0001] The invention relates to the technical field of a static strength test device for a rail transit vehicle body, in particular to a static strength test device for a car body that simulates the impact load of a bogie. Background technique [0002] Rail vehicles (mainly urban rail vehicles and EMUs) car bodies and bogies are often connected by traction seats and traction rods to transmit longitudinal traction or braking force. When the vehicle starts to accelerate or brake to decelerate, the bogie will generate an impact load on the vehicle body due to inertia. Therefore, the impact load of the bogie on the car body is an indispensable key working condition in the computer test of car body static strength. [0003] At present, the impact load test method of rail vehicle bogie on the car body mainly adopts the method of directly loading longitudinal force. That is, a large reaction frame is installed on the ground under the car body, and the longitudinal force ...
