Tribology Eztenics Condition Evaluation Based on Matter Element Theory
The tribo-system has non-linear and random features;it means that the tribo-system output parameters, such as friction coefficient, friction temperature, friction ratio etc. have steady or non-steady random features. Adopting matter element model to describe the tribo-system condition can integrate different types information into a model and realize the quantity expression for the tribo-system. This paper introduced case based reasoning method to evaluate the tribo-system condition based on extenics theory. Tribology condition cases index model was established based on fuzzy similar priority at first. Then through the mutual comparing with all effective elements, the fuzzy similar priority relationship between object case and origin case of rolling bearings were constructed;and the similar serial was obtained under the different affect factors between object case and origin case of rolling bearings. At last the original case was found which was most similar to the object case and the rolling bearing condition could be evaluated. The model integrated indetermination induced by each effective factor and found the original case which was the most similar to the object case from integer. Comparing with the method whose index stratagem was minimal Euclid Distance, the proposal method was more reasonable.
