Abstract

The structure characteristics and the key points in technological design of new type overloaded railway wagon bolster were analyzed.Based on the workshop production condition

the production process was determined.The InteCAST software was adopted to visualize flow field and temperature in filling and solidification process to predict shrinkage hole（porosity）.Finally

the casting process of product was optimized

and completeness of process was realized

so the bolster was produced successfully.
