DESIGN OF EXPERT SYSTEM WITH KNOWLEDGE BASE AS A MODIFIED SLAB METHOD FOR FORGING OF CONNECTING ROD

摘要

The connecting rod is among the most important part used in various engines. With increasing demand for geometrical dimensional accuracy and internal quality, the forging of connecting rod is under investigation. The study deals with an analytical approach in regard to design of knowledge base of an expert system for forging connecting rods. The proposed analytical relations are based on the SLAB method modified by introducing the temperature-dependent flow stress and empirical set of relations for flash dimensions. The overall approach is designed to predict the flash load and cavity load contribution to total load. The cavity stress, flow stress, and principal stresses are also predicted at three different sections of the connecting rod with respect to temperature. The obtained results are verified by a literature comparison and are validated by conducting experiments. The expert system is designed based on the application of VISUAL BASIC language.
