摘要
Abstract
In order to reduce development cycle and test costs of high quality powder metallurgy new products,hip near net-shape forming process of bushing bearing was simulated by Marc.The results show that product geometric dimensions change greatly and the relative density reached 0.98,the local tip position relative density is only 0.85 by the process of forming.In order to improve the local position density and ensure the overall quality of the product,an improvement program by improving the capsule and mold structure,the local increasing in the amount of powder is proposed.The result has provided theoretical guidance for the actual production by numerical simulation.关键词
