Numerical Simulation and Experimental Validation of Squeeze Casting 6082 Aluminum Alloy Automotive Flanges
摘要
Abstract
The numerical simulation of 6082 aluminum alloy automobile flange under different squeeze casting process parameters was carried out,and the location of shrinkage defect was predicted.The results showed that the flange parts were completely filled under each parameter.During the pressure holding process,the corresponding parts of the three bosses were large wall thickness,which finally solidified.After the end of the pressure holding,the temperature of the pressuredregion of the mold was significantly higher than that of other region,and the temperature distribution showed uneven.Attention should be paid to avoid mold damage in the actual process.The shrinkage and dispersed shrinkage mainly appeared in the thick-wall position corresponding to the three bosses,which was consistent with the temperature field results.Excellent castings were obtained from the forming experiments,indicating that the numerical simulation results were correct and reliable.关键词
