The Expert System Of Laser Surface Transformation Harding Based On Database

This study discusses and realizes elementarily the expert system of laser surface transformation hardening, which based on relevant database knowledge system and on basis of two-dimentional heat-conduct analyse models. During the process of using this expert system, pay the utmost attention to using the actual processing technology parameter in the data base; In a situation that have not met the craft parameter that should process initial terms in the database , Consult actual processing technology parameter of the database being handed in and designed , And then use number value to analyse that the model is carried on fictitiously and analyses and process, then modify the result with the processing technology parameter that have been in the database, get an expert with real more significance and consult the craft parameter finally; With the increase of knowledge in the database, the application of this system will be more wide and exact. This system overcomes the shortage due to completely depending on the limited data base knowledge, and overcomes the shortage totally depending on number value of analysing the model the accuracy.To this system mathematics model adopted, we consider model involve metal heat absorption and main reason to conduct heat, carry on the analysis and simulation to calculate in spreading the enthusiasm condition two-dimentionall on this basis. Besides, I think over the practicality and the easiness of account of this model in order to upbuild the expert system easily.The demand and signification of the expert system of laser surface transformation hardening is narrated firstly; and then discuss the model of laser processing detailedly, reason out the calculation expressions with applied worth; In the 3nd chapter, the establish principle of expert system based on relevant database is discussed. In the 4nd chapter, this study introduces the schematic design of this system. In the 5nd chapter, this study discusses the design, realization and use example of each function model. In the last chapter, summarizes the strongpoint and shortage of this expert system, advances the future development direction of this system.
