Example Embodiment

[0026] Example

[0027] figure 1 , 2 It is shown that a specific embodiment of the present invention is: a train dynamic model experiment system, including a line support 1, a test car on the line support 1, 2, and a power device behind the test car 2. The power plant consists of a compressed air ejection mechanism 3, a cart 4 and a flywheel acceleration mechanism. Among them:

[0028] The flywheel acceleration mechanism is composed of multiple flywheels driven by the motor 6 under the rear area of ​​the line support 1. The vertical position of the cart 4 is between the flywheel acceleration mechanism and the line support 1, and the horizontal position is located on the test vehicle 2 and the compressed air ejection mechanism 3, the push rod 4a on the upper surface of the cart 4 passes upwards out of the guide groove 1a of the line support 1 and is aligned with the tail of the test vehicle. The line support 1 in front of the flywheel acceleration mechanism is equipped with a hydrau...

Abstract

The invention provides a train moving die experiment system, wherein the power device is constituted by a compression air ejection mechanism, a barrow and a flywheel accelerating mechanism; the flywheel accelerating mechanism is constituted by a plurality of flywheels driven by a motor below the line support rear area; the vertical position of the barrow is arranged between the flywheel accelerating mechanism and the line support; the horizontal position thereof is arranged between a testing car and the compression air ejection mechanism; the catch bar on the upper surface of the barrow penetrates through a guiding groove of the line support upwards and aligns with the tail part of the testing car; the line support in front of the flywheel accelerating mechanism is provided with a hydraulic barrow interceptor which has the same vertical position with the barrow; and the ejection rod of the compression air ejection mechanism is aligned with the tail part of the barrow. The system has strong power, the testing car has great shape and heavy weight, the testing car can reach a higher speed in a shorter time, the experiment environment is more close to the real conditions and the experiment results are more reliable.

Description

technical field [0001] The invention relates to a train dynamic model experiment system. Background technique [0002] In order to meet the needs of the society, the railway has implemented leapfrog development, and the development of domestic high-speed railway has continuously created new upsurges. While the mileage of the high-speed railway is continuously extending, the speed of the train is also continuously increasing. The maximum operating speed of the Beijing-Shanghai Expressway will reach 400km / h. The increase of train running speed has aggravated the interaction between wheel and rail, as well as the interaction between train and air medium, which has brought many new related problems to the large train system. In order to ensure the high-speed and safe operation of high-speed trains, the aerodynamic performance and collision performance of the trains must be studied, and relevant experimental research on the trains is required. [0003] Due to the high cost of t...
