摘要
以苹果的完整形态为对象，从工程的角度来研究苹果静重损伤的规律。在试验的基础上，通过理论分析得到描述苹果粘弹性特性四单元力学模型，并以此推导出苹果在静重作用下变形的数学模型。利用苹果损伤的能量原理，经回归计算。
From the point of the view of engineering, this paper presents a method to study the apple bruising under static load in real condition. The 4 unit mechanical model of depicting apple viscoelastic properties is obtained through theoretic analysis and ample experiments. A mathematics model, thus, is deduced to present the deformation of apple under static load. Applying the principle of energy of apple bruising, regression equation for the law of apple bruising is set up through regressive computation.
