Description
Technical Field
The invention mainly relates to the technical field of train tests, in particular to a system and a method for testing collision stress behaviors of train passengers.
Background
In recent years, rail transit has been rapidly developed, and in order to improve the safety performance of train operation, it is necessary to study the situation of a train collision. Stress behaviors different from normal stress behaviors are generally generated after passengers feel collision loads during a train collision, and the stress behaviors of the passengers directly influence the collision damage response of the passengers. Therefore, the collision stress behavior of train passengers must be individually studied.
However, because the train passengers are in an unbound state, the damage generated when the train passengers are buckled with the safety belts in a collision mode has great difference, and the characteristics of the train, such as great weight, high speed, coupled connection of a track and an adjacent carriage and the like, determine that the motion characteristics of the train in the collision mode also have great difference with the motion characteristics of the automobile in the collision mode (the train is easy to change direction or even roll due to small inertia), so that the train collision test system cannot be directly applied to research. The existing system and method for researching collision stress behaviors of train passengers all adopt a static simulation form, namely, a volunteer sits in a fixed simulation cabin, a train collision scene simulated by sensing images, sounds and seat vibration is generated to generate stress reaction, and the reaction state of the volunteer is analyzed and researched.
The form of the static simulation is greatly different from the real collision, the reduction degree of the collision is low, and a volunteer can obviously perceive the difference from the real train taking in the test process, so that the psychological state different from the real train taking in is generated. Stress behavior is influenced by psychological states, i.e. different people in different psychological states may perform distinct stress behaviors when encountering the same risk. In the prior art, the psychological state of a volunteer is seriously deviated from the psychological state when a driver actually rides a car in a static simulation mode, so that the stress behavior captured in the test state is greatly different from the stress behavior captured in the real riding state, and finally the accuracy of the test result is low.
