| 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。

| Abstract: | 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 in-dex .Compression force tests were performed by taking a 9 JYK-200 A circular mold briquetting machine as testing appa-ratus 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 15mm and spindle speed of 170r/min,the straw compression force had the optimal value of 20.407KN.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 parame-ters for the research and the analysis of circular mold briquetting machine . |
