| Abstract: | The warpage deformation of the actual product obtained by using three-coordinate measurement and the theoretical warpage deformation by using MoldFlow simulation were compared and analyzed.It discussed the influence of pre-deformation design on the forming accuracy of the water chamber.Finally,the pre-deformation compensation technology was adopted to control the warpage deformation of the car water chamber.The results showed that the maximum warpage error of the product assembly surface after optimization and compensation was reduced from 1.24 mm to 0.47 mm,which met the product design accuracy requirements. |
