[0033] Working principle:

[0034] The test device realizes quick switching of different road conditions through a modular design, and the core working principle is as follows: when it is necessary to change the road surface characteristics of the U-shaped simulation runway 1, the control system will accurately start the drive motor corresponding to the target road surface type, the drive motor realizes power transmission through the shaft coupling and the reciprocating lead screw 6, and drives the reciprocating lead screw 6 to perform accurate axial rotary motion. Under the action of screw transmission, the connecting block 7 forming a kinematic pair with the reciprocating lead screw 6 starts to move linearly along the guide rail, and the movement of the connecting block 7 drives the first moving plate 3 to move out of the internal cavity of the control bin 2 stably. In this process, the extension end of the first moving plate 3 keeps horizontal motion under the constraint of the guide mechanism until the end away from the connecting block 7 forms a close mechanical abutment with the side of the U-shaped simulation runway 1, at this time the first moving plate 3 completely covers and fits on the upper end surface of the U-shaped simulation runway 1, forming a continuous and smooth test plane. When it is necessary to switch to the road condition corresponding to the second moving plate 4, the system will start another set of independent drive motor, which makes the second moving plate 4 move horizontally on the upper end surface of the first moving plate 3 through the same transmission mechanism, in this moving process, the roller 5 installed at the bottom of the second moving plate 4 forms rolling contact with the upper surface of the first moving plate 3, which not only provides stable support force for the second moving plate 4, but also significantly reduces the friction resistance in the moving process, ensuring the stability and reliability of the road surface switching process. In order to simulate the wet and slippery road conditions, the spraying assembly equipped with the device forms a uniform water curtain cover through a plurality of spraying pipes 11 arranged in a distributed manner, the nozzles of the spraying pipes 11 are optimized in fluid mechanics, which can uniformly spray water medium on the target road surface at a specific flow rate and pressure, accurately reproduce the change of the adhesion coefficient under the wet and slippery road conditions, and comprehensively test the dynamic response performance of the emergency vehicle under different road condition characteristics. The whole system realizes quick and accurate switching of road surface characteristics and controllable simulation of environmental conditions through mechatronics design.
