    摘要:

    對影響生物質(zhì)液壓成型的主要因素進行了分析及試驗,,通過木屑成型試驗表明,最佳含水率范圍應(yīng)控制在0.15~0.18。在此基礎(chǔ)上運用FEA分析軟件ANSYS對成型過程中生物質(zhì)的流變特性進行有限元模擬,,分析了整個成型過程中生物質(zhì)位移和應(yīng)變演變特性,,得到生物質(zhì)在材料致密化過程中摩擦力的變化規(guī)律,,為生物質(zhì)的成型機理研究提供了依據(jù),。

    Abstract:

    The primary factor of influencing the process of biomass hydraulic briquetting was analyzed and studied. The experimental result indicated that the best range of containing water ratio was 0.15~0.18. Based on the results, the simulation of the process of biomass hydraulic briquetting was carried out with the finite software ANSYS at first. Then the displacement and strain in the biomass extrusion process was analyzed, and the rule along with the disciplinarian of frictionchanging in the process was obtained. All these provided credible conditions for the study of biomass briquetting mechanism. 
