刀豆脱壳力学特性的实验研究

Experimental study on mechanical properties of Canavalia

  • 摘要: 利用万能试验机对刀豆的力学特性进行压缩实验。选择破壳力、破壳变形量和破壳能量为实验指标,以刀豆宽度、厚宽比、含水率、加载位置和试验机的施压速率为因素进行了混合水平正交实验和回归分析。结果表明,当沿荚果纵脊面平行压缩时,破壳效果理想,为脱壳的有效加压方向。含水率对破壳力和破壳能量的影响极显著,呈非线性正相关关系,降低含水率有利于提高脱壳率和减少设备能耗。加载位置、宽度和厚宽比对破壳变形量有显著影响,破壳变形量总体上随宽度和厚宽比的增大而减小。刀豆破壳力和破壳能量的综合最优水平组合:加载位置为中部,含水率为14.6%,施压速率为20mm/min。 

     

    Abstract: The mechanical properties of Canavalia were investigated by a universal testing machine under compression load.The test mechanical properties in terms of the rupture force, rupture deformation, and rupture energy required for initial rupture were considered as the dependent variables. The mixed - level orthogonal experiments and regression analysis were carried out with five independent variables, which included pod width, moisture content, thickness - width ratio, compression location and loading rate of testing machine. The results showed that when the compression direction was transversely in width direction and along longitudinal ridge surface of bean pod can obtain desired shelling efficiency.Moisture content had a significant effect on rupture force and rupture energy, and the negative nonlinear relationships between them were observed. To improve shelling efficiency and reduce energy consumption of shelling equipment, the moisture content should be reduced. The compression location, pod width and thickness- width ratio had highly significant effect on rupture deformation. The rupture deformation generally decreased by increasing pod width and thickness - width ratio. The preferred rupture parameters for rupture force and rupture energy were at compression location of middle pod part, moisture content of 14.6% and loading rate of 20mm /min, respectively.
