    摘要:

    運(yùn)用ANSYS有限元理論對(duì)秸稈類生物質(zhì)成型徐變過程進(jìn)行模擬分析,，根據(jù)其生物機(jī)理和化學(xué)成分建立生物質(zhì)徐變有限元模型,，生成接觸對(duì),，通過非線性大變形分析得到成型徐變規(guī)律和成型壓力-變形關(guān)系,。結(jié)果表明生物質(zhì)冷成型徐變過程包括松散、壓緊、固化3個(gè)階段，是塑性變形和粘性變形的結(jié)合,。

    Abstract:

    Simulation analysis of molding process for straw biomass was carried based on ANSYS. The mechanics mold was established according to its biology mechanism and chemical component, along with contact pairs. Then molding rules and relations between pressure and deformation were obtained through nonlinearity analysis. The analysis results showed that biomass molding under general condition process included three stages: loose, compaction, solidification, which combined the plastic deformation with the viscous deformation. The obtained results are well in agreement with experiment data.
