Analysis and Optimization of Warping Deformation of Automotive Center Console Frame Based on Moldflow
Taking a certain car's central console frame as the research object,it was found that the warping deformation of the sample exceeded the assembly requirements.The actual injection molding process of the plastic part was simulated via Moldflow software.The maximum error between the simulated value and the average measured value of the warping deformation was 5.98%.It was discovered that the main factors leading to the warping deformation of the plastic part were uneven cooling and shrinkage.In this study,glass fibers with a mass fraction of 25%were added to the raw materials,and the process parameters were optimized.The results show that the simulated value of the warping deformation decreases by 86.22%compared to the initial one.Prototype verification indicates that the maximum error between the simulated value and the average measured value of the optimized warping deformation is 4.35%,proving the accuracy of the Moldflow software simulation analysis.After prototyping,the maximum warping deformation of each measurement point is reduced to less than 1.6 mm,which is reduced by more than 80%compared with the initial one,providing insights for the analysis and optimization of warping deformation for similar large and complex injection-molded parts.
