Assembly Accuracy Based Tendency Analysis and Predicting Method for Product Behavior

In the process of product manufacturing, control of assembly accuracy will directly affect product working behavior. Variation of working behavior with assembly accuracy was partitioned to three phases: compensation phase, rapid loss phase and total loss phase. Based on changing curve of product behavior, Function of behavior loss was constructed to describe behavior loss resulting from assembly error of a part of product. The conception and calculating method of behavior loss index (BLI) are given to reflect behavior changing status of whole product under certain assembly accuracy. Taking BLI value for reference, next measurement adopted can be determined. Finally, an example was used to demonstrate calculating procedure of BLI.
