| Abstract: | In this paper,the grid node coordinate adjustment algorithm was proposed based on Displacement Adjustment.The principle of the algorithms and compensation formulas was presented in detail,and the principle of determining the compensation coefficients in the formulas was given.Finally,the simulation model of the age-forming was established to simulate the process and the grid node coordinate adjustment algorithm was applied to compensate the mold surface.The precision of the part in the third simulation met the design requirements.Then,this method was used in the compensation for the skin-panel's mold.The experiment results proved that the grid node coordinate adjustment algorithm was reliable. |
