Technical Field

[0001] The utility model relates to the technical field of a bogie secondary suspension system, in particular to a dynamic multi-component device. Background Art

[0002] The bogie secondary suspension system is an important component of the train bogie. It is mainly used to connect the bogie to the car body, and plays the role of supporting the weight of the car body, shock absorption and guidance. The bogie secondary suspension system usually consists of the following parts: spring device, shock absorber, lateral stabilizer, guide device, etc. The design and selection of the bogie secondary suspension system have an important impact on the running performance of the train. When designing, it is necessary to fully consider factors such as the train's running speed, load capacity, and curve passing ability to ensure that the performance of the suspension system meets the requirements. At the same time, the suspension system also needs to be tested, verified and optimized to improve the running stability and comfort of the train.

[0003] A dynamic multi-component device is a device used to measure and analyze the dynamic interactions of a multi-component system. In the fields of chemistry, physics, biology, etc., a dynamic multi-component device can help people understand the interactions between the components in a multi-component system and the effects of these interactions on the properties and behaviors of the system.

Generally, it is only compressed to a fixed degree, and the test result is relatively simple, which will affect the accuracy of the test result. In view of the above problems, it is necessary to improve the existing equipment. Utility Model Content
