Embodiment 1

[0032] Such as Figure 1 to Figure 3 As shown, in the first embodiment of the train crash test waveform simulation system of the present invention, it includes: a waveform controller 1 and a trolley 2;

[0033] The waveform controller 1 includes a pair of pedestals 11 mirrored on both sides of the traveling direction of the trolley 2, and the pedestals 11 are fixedly connected to the foundation; the side of the pedestal 11 facing the trolley 2 is provided with an upper support seat 12 extending along the traveling direction , and an upper friction plate 13 is installed under the upper support seat 12;

[0034] The trolley 2 is provided with side wings 21 on both sides along the traveling direction; the upper surface of the side wings 21 can rub against the lower surface of the upper friction plate 13 to reduce the speed of the vehicle to simulate a collision waveform.

[0035] By setting the upper support seat 12 and the upper friction plate 13 on the waveform controller 1 ar...

Embodiment 2

[0037] Such as Figure 4 As shown, the second embodiment of the train crash test waveform simulation system of the present invention, the waveform simulation system is basically the same as Embodiment 1, the difference is:

[0038] In this embodiment, the upper support seat 12 and the upper friction plate 13 are connected by lower jacking bolts 31 and lifting bolts 32 alternately distributed along the traveling direction;

[0039] The tail of the lower jack bolt 31 passes through the upper support seat 12 and abuts against the upper friction plate 13, and the lower jack bolt 31 can push the upper friction plate 13 away from the upper support seat 12;

[0040] A countersunk groove is formed on the lower surface of the upper friction plate 13, the head of the lifting bolt 32 is embedded in the countersink groove, and the tail part passes through the upper support seat 12, and the upper friction plate 13 can be pulled closer to the upper support seat 12 by the lifting bolt 32;

Abstract

The invention discloses a train collision test waveform simulation system. The system comprises a waveform controller and a trolley. The waveform controller comprises a pair of pedestals arranged on the two sides of the advancing direction of the trolley in a mirror image mode, and the pedestals are fixedly connected with a foundation, upper supporting seats extending in the advancing direction are arranged on the sides, facing the trolley, of the pedestals, and upper friction plates are installed below the upper supporting seats; and the two sides of the trolley in the advancing direction are each provided with a side wing, the upper surfaces of the side wings can rub with the lower surfaces of the upper friction plates to reduce the vehicle speed so as to simulate collision waveforms. Compared with the prior art that a hydraulic control device and a control buffer device need to be synchronously matched, the system can achieve a collision simulation effect just in a friction mode. Compared with the prior art, the structure of the system is simpler, the implementation difficulty is greatly reduced, and the test cost can be more effectively controlled, and the test reliability is improved.

Description

technical field [0001] The invention mainly relates to the technical field of train crash test devices, in particular to a train crash test waveform simulation system. Background technique [0002] "Safety" is the foundation of train operation. With the rapid development of the rail transit industry, while improving the active safety of trains, more and more attention has been paid to the passive collision safety performance of rail vehicles. There are various forms of damage in train collision accidents, and the casualties caused by collisions are shocking. The unrestrained state of train occupants further intensifies the risk of collision casualties between them and the interior of the train. The study of the dynamic response of train occupants to secondary collisions is of great significance for improving the passive safety performance of trains. Significance. [0003] The secondary crash test of rail vehicle occupants is an indispensable research method to study the cr...
