Research on the Online Quality Control of Engine Assembly Based on Self-organizing Map

According to the discussion about characteristic, topological structure and learning arithmetic of the self-organized mapping(SOM) neural network,this paper presents an ideal of using SOM neural network in the online quality control of engine assembly and introduces a method based on SOM neural network,which is studied by using the single sample and diagnosing the multiple quality problems of the online engine according to the position of output nerve cell.By analyzing the samples,the method is proved to be available for diagnosing the multiple quality problems of engine assembly.
