Abstract


With the Ministry of Railways ' heavy freight and passenger high speed \I follow the direction of development of railway transport , independently developed a semi-mounted high-speed locomotives as well as with American co-production of EMD EMD locomotive power and other projects . In locomotive manufacturing industry , housing castings is widely used, especially in locomotive diesel engine main bearing , axle housing and other key parts of locomotives . Casting quality will directly affect the overall performance of the locomotive . As more and more companies will be Pro / ENGINEER and MAGMA software applications to actual production . By analyzing the mold filling and solidification process of numerical simulation results , we can predict casting defects , thus optimizing the casting process parameters to ensure the quality of castings and shorten trial period and reduce production costs. In this paper, Pro / ENGINEER software for the pre-processing platform to MAGMA software simulation platform to study the box-type parts of the casting process . Combined with actual plant production needs, and the bracket on the axle housing casting process scheme for numerical simulation analysis to the gating system and feeding system , focusing on prediction of casting defects , remedial measures taken in advance , by comparing the simulation results with the trial results , the casting process parameters and programs to optimize the design , and achieved good results. While improving production efficiency, improve product quality ! For post production and laid a solid foundation.
