Embodiment

[0028] Figure 1~2 Shown: a kind of embodiment of this invention is: a kind of train bogie high-frequency impact test bench, comprises the train bogie (1) that test is used, the small wheel pair (2) that the bogie (1) bottom rotates at high speed ), the small wheel pair (2) is fixed in the pit of the concave foundation (4) by the wheel pair support (3), and one end of the small wheel pair (2) is connected with a gear box (5), and the gear box (5) The other end of the motor (6) is connected. It is characterized in that: the high-speed rotating small wheel set (2), the wheel set support (3), the gear box (5) and the motor (6) are all installed in the pit of the concave foundation (4). Said bogie frame (1) is placed on the small wheel pair (2) and the concave foundation (4) top.

[0029] image 3 and figure 1 Show: the specific composition of the small wheel pair (2) of this example is: the shaft (2a) is fixedly connected with the two wheels (2b), and there are evenly distrib...

Abstract

The invention relates to a high-frequency impact test stand for a train bogie. The high-frequency impact test stand for the train bogie is characterized by comprising the train bogie (1) used for testing and a trundle set (2), the trundle set (2) is arranged at the lower portion of the train bogie (1), rotates at a high speed, and is fixed in concave pits of a concave foundation (4) through trundle set supports (3), one end of the trundle set (2) is connected with a gearbox (5), the other end of the gearbox (5) is connected with a motor (6), the trundle set (2) rotating at a high speed, the trundle set supports (3), the gearbox (5) and the motor (6) are installed in the concave pits of the concave foundation (4), and the train bogie (1) is placed above the trundle set (2) and the concave foundation (4). The train bogie fixing mode is the same as the restraining mode of a real line train running mode, and test stress and restraint authenticity is ensured.

Description

technical field [0001] The patent of the present invention relates to a high-frequency impact test bench for train bogies. Background technique [0002] The development of railway transportation to high-speed and heavy-duty has aggravated the vibration of the train running, the service environment of each component has deteriorated, and the structural strength problems exposed to the bogie, wheel axle and car body have gradually increased, especially in the light structure required by high-speed trains. After quantification, the problem of structural strength will be more prominent. [0003] Moreover, after the train running speed is greatly increased, the frequency of external disturbances increases sharply, causing high-frequency vibration shocks with frequencies exceeding 500 Hz, 50 Hz and 25 Hz and above on the wheel set, frame and car body respectively. The operation safety and reliability problems caused by high-frequency vibration shock are one of the problems to be ...
