【摘要】：以聚碳酸酯(PC)為薄膜材料,采用有限元方法對儀表盤外殼模外裝飾(OMD)貼膜成型進(jìn)行仿真,得到薄膜厚度的分布及其在x、y方向上的變形分布,在此基礎(chǔ)之上,以三者的標(biāo)準(zhǔn)偏差同時最小來設(shè)計目標(biāo)函數(shù),采用試驗設(shè)計的方法來建立近似模型,最后對貼膜工藝參數(shù)進(jìn)行全局優(yōu)化分析。結(jié)果表明,基于橢圓向基神經(jīng)網(wǎng)絡(luò)模型(EBF)模型采用自適應(yīng)模擬退火算法(ASA)全局優(yōu)化算法對OMD工藝參數(shù)進(jìn)行優(yōu)化分析所得到的結(jié)果無論在厚度分布還是變形精度上的效果都最好。
[Abstract]:Using polycarbonate (PC) as thin film material, finite element method (FEM) was used to simulate the forming of OMD-coated instrument panel shell. The film thickness distribution and its deformation distribution in XY direction were obtained. On the basis of the simulation, the film thickness distribution and the deformation distribution in XY direction were obtained.The objective function is designed with the minimum standard deviation, the approximate model is established by the method of experimental design, and the global optimization analysis of the process parameters is carried out.The results show that the global optimization algorithm based on the Elliptic basis Neural Network (EBF) model and the adaptive simulated annealing algorithm are used to optimize the process parameters of OMD. The results are the best in both thickness distribution and deformation accuracy.
