摘　　要：为研究油茶果壳的破壳力学特性,探究油茶果壳如何破裂,对油茶果的几何特性参数进行测量,为油茶果破壳机提供理论支持。使用TMS-PRO质构仪对油茶鲜果进行力学特性试验,运用SolidWorks对油茶果进行建模,并运用ANSYS Workbench对油茶果进行模拟破壳试验。结果表明:油茶果的球度系数为0.94,可以近似于球体模型进行研究,沿油茶果纵向方向加载最省力,直径和加载速率对破壳力的影响显著,剪切破壳力约为挤压破壳力的35%;通过有限元分析显示应力主要集中于压缩板与油茶果接触边缘部分,外壳总形变为6.372 mm,可以达到破壳需求。In order to study the mechanical properties of oil tea fruit shell breaking,investigate how the oil tea fruit shell breaks,measure the geometric characteristics parameters of oil tea fruit;provide theoretical support for the oil tea fruit shell breaking machine.Used TMS-PRO texture meter to test the mechanical properties of oil tea fresh fruit,used Solid Works to model the oil tea fruit,used ANSYS Workbench to simulate the shell breaking of oil tea fruit.The results showed that:the sphericity coefficient of oil tea fruit 0.94,which can be approximated as a sphere model,the loading along the longitudinal direction of oil tea fruit was the most energy-saving,the influence of diameter and loading rate on the shell breaking force was significant,the shear shell breaking force was about 35%of the extrusion shell breaking force,the finite element analysis showed that the stress was mainly concentrated in the contact edge part between the compression plate and oil tea fruit,and the total shell deformation was 6.372 m,which can meet the shell breaking requirement.
