With the development of the automobile industry , the increasingly high demand for cars driving handling and ride comfort . The suspension system 's function is to support the body , improve the ride feel different suspension settings will make the driver has a different driving experience . Suspension performance is good or bad , will not only directly affect the vehicle ride comfort , ride comfort , driving safety and the car's handling and stability , through sexual and fuel economy have different levels of impact . Due to the complex structure of the suspension system , installed in a unique position , fault diagnosis is very difficult . Suspension fault diagnosis is still stuck in the diagnosis of human experience ; This is not only a waste of time , and improper repairs can cause new failure , increased maintenance costs , so important suspension fault diagnosis system . This paper mainly around the fault detection and diagnosis of car suspension to start the study. First, the analysis of the performance of the detection method of fault diagnosis overview as well as suspension of the suspension at home and abroad . The suspension structure and its characteristics as the basis for suspension of common failure mechanism , determine fault phenomenon and fault location . Again , through the analysis of a large number of real vehicle tests and maintenance enterprises failed instance , to find out the regularity of suspension failure , combined with on-site diagnostic steps to draw a suspension system fault diagnosis flowchart . Finally, on the basis of the foregoing study establish the suspension fault diagnosis system . The system uses the experimental test parameters analysis combined with expert advice , the user simply prompted by the system simple , you can achieve the purpose of rapid diagnosis of suspension failure . The system used in the repair business, reduce the suspension fault diagnosis for the requirements of the technical staff , has a strong practical , easy to use promotion . With the development of the automobile industry , to maintain the amount of the increase will generate social and economic value .
