摘  要：
试验采用四因素五水平二次回归正交旋转中心组合设计法,以水稻秸秆和稻壳为原料,主轴转速、含水率、稻壳含量和秸秆长度为试验影响因子,秸秆压缩力为试验指标,利用9JYK-2000A型环模秸秆压块机进行秸秆压缩力试验研究。结果表明:当主轴转速为170r/min、含水率为20%、稻壳含量为30%、秸秆长度为15mm时,秸秆压缩力有最佳值为20.407k N;各因素对环模秸秆压块机秸秆压缩力贡献率主次顺序依次为:含水率>秸秆长度>稻壳含量>主轴转速。试验验证可知:该组合下试验值与试验模型预测值之间相对误差平均值为1.9 4%,可以为环模秸秆压块机压缩机理研究和分析提供必要的参数依据。

摘  要：
Experiment is designed as quadratic regression orthogonal of four factors and five levels,which takes spindle speed,moisture content,rice husk content and straw length as influence factors,and straw compression force as test index. Compression force tests were performed by taking a 9JYK- 200 A circular mold briquetting machine as testing apparatus with rice straw and rice husk as raw material. The result indicated that when the raw material had moisture content of 20%,rice husk content of 30%,straw length of 15 mm and spindle speed of 170 r / min,the straw compression force had the optimal value of 20. 407 KN. The order of contribution rate of every experiment factor on target index was obtained as follows: moisture content,straw length,rice husk content,spindle speed. The verification of the experiment shows that the relative error between the predictive values and experimental values is 1. 94%,which can provide the necessary parameters for the research and the analysis of circular mold briquetting machine.
