Abstract: On the basis of traditional casting technology,a rapid casting technology based on Pro Cast and 3D pringting technology was studied. The casting process numerical simulation is conducted with Pro CAST software,the filling of the Brake Shoe,and temperature fields and flow fields during solidification were simulated,and the casting process of the Brake Shoe was optimized depending. And then a Brake Shoe model was produced by 3D pringting technology,the mold manufacturing process was eliminated. The results indicate that effective combination of traditional casting technology and numerical simulation and 3D pringting technology can shorten manumacturing cycle and improve economy benefits.
Keywords: numerical simulation; 3D printing; brake shoe
