摘要
对影响生物质液压成型的主要因素进行了分析及试验,通过木屑成型试验表明,最佳含水率范围应控制在0.15～0.18。在此基础上运用FEA分析软件ANSYS对成型过程中生物质的流变特性进行有限元模拟,分析了整个成型过程中生物质位移和应变演变特性,得到生物质在材料致密化过程中摩擦力的变化规律,为生物质的成型机理研究提供了依据。
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.
