Problems solved by technology

[0004] The first purpose of the present invention is to provide a test device that is simple in structure, easy to assemble and disassemble, and can effectively meet the impact test method of the EMU sand box anti-dropping seat, and then obtain reliable, effective and accurate test data. Dismounting vibration and shock test device to solve the problem that there is no suitable test device at present, and thus it is impossible to obtain reliable, effective and accurate test data
[0005] The second purpose of the present invention is to provide a vibration shock test method for the sand box anti-off seat of the EMU sand box, which is simple in structure, easy to assemble and disassemble, and effectively improves the reliability and accuracy of the impact test of the anti-off seat of the sand box, so as to solve the current problems. There are suitable test methods, and thus the problem of not being able to obtain reliable, valid and accurate test data

Abstract

The invention relates to the technical field of rail vehicles, and particularly to a sandbox anti-falling seat vibration impact testing device of Multiple Units and a method thereof. The sandbox anti-falling seat vibration impact testing device comprises two first supporting units and one second supporting unit. Each first supporting unit comprises a first transverse supporting beam for supporting a sandbox. Furthermore the connecting part between the first transverse supporting beam and the sandbox is provided with a height-adjustable adjusting gasket. The second supporting unit is provided with a frame mounting beam, a sandbox mounting beam for mounting the sandbox, and an anti-falling seat mounting frame which is connected with the frame mounting beam and is used for placing an anti-falling seat. The anti-falling seat mounting frame is arranged below the sandbox mounting beam. The sandbox anti-falling seat vibration impact testing device has advantages of simple structure, high convenience in mounting, and flexible adjustment for distance between the sandbox and the combining force of the anti-falling seat, quick and efficient clamping positioning in vibration impact testing of the sandbox anti-falling seat, high reliability in testing controlling, and high accuracy of testing data.

Description

technical field [0001] The invention relates to the technical field of rail vehicles, in particular to a vibration and shock test device and method for an EMU sand box anti-disengagement seat, and in particular to a vibration and shock test device and method for an anti-disengagement seat of a sand box with a simple structure, which is easy to assemble and disassemble and effectively improves the reliability of the vibration and shock test for an anti-disengagement seat of a sand box The vibration and shock test device and method of the EMU sand box anti-detachment seat and the accuracy. Background technique [0002] The anti-loosening seat of the sand box is an important part to prevent the sand box from falling off under the high-speed EMU. It can drive safely when the sand box falls off, and is an important part to ensure the safety performance of the vehicle. The sand box of an EMU is installed under the underframe of the car body. In order to ensure safety, an anti-loos...
