Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The present invention firstly discloses a train occupant collision stress behavior test system. In one embodiment, the test system includes: a test car body, a monitoring device and a braking device;

[0036] The test car body includes compartments that are visually arranged according to the interior space of the operating train. Volunteers can ride in the compartments; a protective mechanism is installed in the compartments to protect the personal safety of volunteers when a simulated collision occurs; the test car body can ride along the Drive on a preset route;

[0037] The monitoring device is installed on the body of the volunteer or in the compartment, and the monitoring device is used to collect the stress behavior data of the volunteer when the simulated collision occurs;

[0038] The braking device is located at the e...

Abstract

The invention discloses a train passenger collision stress behavior test system and method. The system comprises a test train body, a monitoring device, and a braking device. According to the invention, a dynamic simulation form is adopted, and friction braking is performed between the test train body capable of running along the preset path and the braking device so as to simulate the collision effect. Compared with the prior art that stress behavior data is collected in a static simulation form, the collision effect is more real, the compartment arrangement is consistent with the internal space of an operating train, volunteers are personally on the scene, the psychological state of real riding can be better restored, more natural stress behaviors can be generated, further test data closer to the real riding state can be captured by the monitoring device, and the test accuracy is improved.

Description

technical field [0001] The invention mainly relates to the technical field of train testing, in particular to a system and method for testing train occupant collision stress behavior. Background technique [0002] In recent years, rail transit has developed rapidly. In order to improve the safety performance of train operation, it is necessary to study the situation when trains collide. During a train collision, the occupants usually have different stress behaviors after feeling the collision load. Existing studies have shown that the occupant's stress behavior will directly affect the occupant's response to collision damage. Therefore, a separate study of the crash stress behavior of train occupants is necessary. [0003] However, since the train passengers are in an unrestrained state, there is a huge difference in the damage caused by the collision with the car passengers wearing seat belts, and the characteristics of the train such as heavy weight, fast speed, and the c...
