The means of transportation has become the first choice for people to go to and from various places, and railway vehicles are one of the important systems, providing passenger transport services. However, without a good vibration-absorbing system, passengers will feel uncomfortable at high speeds, so the design needs to provide a comfortable ride quality. For this reason, the railway vehicle has added a so-called suspension system to the bogie, and named it "primary suspension" and "secondary suspension". The vibration energy will be transmitted to the car body through the bogie, and the secondary suspension can absorb the vibration energy again to improve the ride quality. Now we are going to discuss the secondary suspension. Generally, two air springs are often used in the secondary suspension The side frames installed on both sides of the bogie respectively support the car body.
