【摘要】：采用FORTRAN語(yǔ)言設(shè)計(jì)編寫DSGZ黏彈性本構(gòu)模型的材料子程序嵌入至ABAQUS軟件中,然后基于模外裝飾工藝原理,對(duì)六個(gè)鼠標(biāo)外殼貼膜工藝成進(jìn)行模擬計(jì)算,成型后薄膜的最薄厚度為0.183 mm,薄膜在X方向最大變形量為7.417 mm,薄膜在Y方向最大變形量為4.107 mm。通過(guò)增大鼠標(biāo)之間的左右距離同時(shí)減小鼠標(biāo)之間的前后距離,改進(jìn)之后薄膜的最小厚度為0.184 3 mm,薄膜在X,Y方向上的最大變形量分別為7.104,2.574 mm,其較改進(jìn)前分別減少了4.22%,37.3%。
[Abstract]:The material subprogram of DSGZ viscoelastic constitutive model is programmed by FORTRAN language and embedded into ABAQUS software. Based on the principle of external decoration, the process of six mouse shells is simulated and calculated. The thinnest thickness of the formed film is 0.183 mm, the maximum deformation in X direction is 7.417 mm, and the maximum deformation amount in Y direction is 4.107 mm. by increasing the distance between the mouse and the left and right, the distance between the front and the rear of the mouse is reduced. The minimum thickness of the modified film is 0.1843 mm, and the maximum deformation of the film in the XY direction is 7.104 mm and 2.574 mm, respectively, which is less than that before the improvement by 4.22% and 37.3 mm, respectively.
