Universal aluminum section vehicle end fixing device

Abstract

The invention relates to an end wall fixing device in rail vehicle end relation tests, and particularly to a universal aluminum section vehicle end fixing device. The device comprises a cast iron T-groove pedestal platform, a vehicle end support counterforce framework assembling body, a flexible variable support end wall assembling body and a flexible vehicle end edge assembling body; the vehicle end support counterforce framework assembling body is fixed on the cast iron T-groove pedestal platform; the flexible variable support end wall assembling body and the vehicle end support counterforce framework assembling body are in fixed connection through a three dimensional force transducer assembling body; and the flexible variable support end wall assembling body and the flexible vehicle end edge assembling body are in fixed connection through a vehicle end wall connection arm supporting structure assembling body. The invention discloses a universal variable aluminum section vehicle end fixing device that can be assembled and installed conveniently. According to the fixing device, the cable connection points among trains and the installation position of a force cell can be adjusted; the shape and dimension of the end wall can be adjusted according to a detected vehicle model; the rigidity can meet experiment requirement; and the versatility is high.

Description

technical field [0001] The invention relates to an end wall fixing device used for the test of the relationship between rail vehicle ends, in particular to an ever-changing aluminum section bar end fixing device. Background technique [0002] The car end is an indispensable and important device in the composition of rail vehicles, which plays the role of connecting each car and making it pass through various curves and curves smoothly under the drive of the train. The performance of the train end directly affects the running quality and safety of the EMU train. The car end relationship test refers to the relative movement and rotation of the parts installed at the end of the car body during the operation of the train due to the relative movement and rotation of the parts of the train body and when passing through the curve. By measuring the displacement and force of the parts To measure the stiffness and damping parameters of the train end, and provide accurate data for the...

AI Technical Summary

Problems solved by technology

[0003] At present, there are still relatively few experimental devices for vehicle-side relationship, and the relevant theoretical knowledge is not perfect enough.

Especially for the fixing device of the car end wall, there are many shortcomings such as the combination installation is not convenient enough, the cable connection point adjustment between trains is not convenient enough, the installation position adjustment of the load cell is not convenient enough, the rigidity cannot meet the test requirements, and the versatility is poor.

The relevant patent of the rail vehicle vehicle-end relationship test bench has the invention name "rail vehicle vehicle-end relationship comprehensive test platform", the applicant is Jilin University, the Chinese patent authorization announcement number is 102226743A, and the designed vehicle end wall fixing device has insufficient combined installation Convenience, the adjustment of the cable connection point between trains is not convenient enough, the installation position of the load cell is not convenient enough to adjust, and the rigidity cannot meet the test requirements, etc.

The name of the invention is "Comprehensive Test Bench for Vehicle-End Relationship", the applicant is Harbin Institute of Technology, and the Chinese patent authorization announcement number is 102128723A. The fixed device of the vehicle end wall designed in it cannot complete the connection of different structures and sizes of the vehicle end wall. The adjustment of the cable connection point is not convenient enough, the installation position of the load cell is not convenient enough to adjust, and it is impossible to realize a more realistic two-way loading simulation on the vehicle end, etc.
