Abstract:

This paper puts forward the diagnosis method based on fuzzy mathematics, introduces fuzzy mathematical method into the suspension fault diagnosis, and analysis the ambiguity relationship between the fault symptom and fault reason, establishes a fuzzy comprehensive evaluation model of the suspension fault diagnosis. And by means of the state parameters method, set up the membership function model and evaluate the suspension system comprehensively according to the Maximum Subordination Principle. The typical examples show the accuracy and practicality of the model.

Key words: automobile engineering, suspension system, fault diagnosis, fuzzy mathematics, maximum subordination principle
