Ductile Iron-Automotive Steering Knuckle's Casting Technology And Computer Analysis And Stimulation

Ductile iron have good mechanical capability, especially in automobile industry .Because of the low price and good performance, ductile iron have replaced the cast steel in some aspect. But, there is a special process of ductile iron, namely graphite . In this process, there are Shrinkage and dispersed shrinkage.In this thesis, making use of foundry theory which is usual and practical , considering the situation in factory. To sign a practical and useful casting system is to avoid the Shrinkage and dispersed shrinkage.In this process, using the computer technology, the analysis software-JSCAST analyze the casting process and validate the design. The main work of this thesis is:1 According to the casting design theory, to compute the coefficient. Then, to make use of other designer' experience and to modify the casting technics.2 Using of the computer, the analysis software-JSCAST can analyze the result of casting. According to the result, to modify the casting technics. In this process, we can expedite the research and development and reduce the charge and time of new product.
