Design and Optimization of Casting Process for Lower Box of Urban Rail Gear
For the casting of the lower box of the urban rail gear,UG 3D software is used to calculate and determine the key module Ms of the casting;Adopt proportional solidification technology to design pouring and pouring system;Based on Procast numerical simula-tion software,the mold filling and solidification process numerical simulation is carried out,the location of shrinkage porosity and shrink-age cavity problems in the solidification process is effectively predicted,and the casting process plan is optimized to shorten the trial production cycle of new products and reduce production costs.
