The dynamic, mechanical behaviour of a chicken egg is assessed. Experimental modal analysis tests revealed several spherical modes in the 2– frequency band. An identification of the mode shapes, the resonant frequencies and corresponding damping ratioses of these modes is obtained. The study allows the interpretation of the vibration response of an egg excited at its equator with a light mechanical impact which could open the door towards an automated egg inspection system.

我们评估了鸡蛋的动力学和机械行为。模态分析实验在两个频率段的几个球形模型情况，获得了这些模式的模式形状识别特征，共振频率以及相应阻尼比率。研究表明，解读由轻度机械冲击激发的鸡蛋赤道部位的震动响应，为研究自动蛋品检测系统提供了一种新方法。
