Abstract
Suspension is one of the important components of automobile products, and the smooth operation of the automobiles is closely related to the structure of the suspension. This paper studies the semi-active suspension control and its performance test by firstly introducing the suspension, then analyzing the neural network control basis and designing the single-chip control system, and finally formulating the performance evaluation criteria of suspension to evaluate its function. The performance of the semi-active suspension built on the basis of neural network control theory is better than that of the passive suspension and active suspension, so it can be promoted in the future application.
Highlights
The unevenness of the road will cause the irregular vibration of the car in its traveling process, which has great side effects for both people and goods on the car
This paper conducts a research on the application of semi-active suspension control and performance testing system after the introduction of the concept and the classified comparison of automotive suspension, hoping to provide a reference and contribution to the development of automobile manufacturing [2]
The control system of suspension structure is expected to have the following functions: the single-chip control system receives the operation state signals of the vehicle, which are not from the multi-way switch but collected by multi-sensors; the function of the magnified circuit and filter circuit in the control system is to process the signals input into the system; the signals input into the system, presented in the form of data, will be converted by the control system, and the binary number will be converted to three byte floating point
Summary
There is a certain relationship between the frame and the axle of the car, and it is the suspension that plays the role of connection. The role of suspension has been briefly described above, and it will be analyzed from three aspects: Firstly, in the running process of the vehicle, several kinds of forces will be transmitted to the wheels, including the reaction force in the vertical direction, the driving force from the engine, the braking force from the braking system and other vertical or lateral forces. The interaction of these forces and their transmission on the parts of the vehicle may produce other forces, which will eventually be acted on the vehicle, producing vibration of the whole bearing system of the vehicle [4]. The passive suspension is no longer that popular when the driving environment and the people have higher requirements for its stability
