我们研究评估了鸡蛋的动力、机械行为。试验模块分析检测表明在2个波段有几种球形模式。要鉴别模型形状，获得了这几种模式的谐振频率和相应阻尼比。高通量蛋品质测定仪研究表明，可通过轻微机械力施加在鸡蛋赤道处，激发振动并对振动加以诠释，该研究为研发自动蛋品检测系统敞开了大门。

Experimental analysis of the dynamic, mechanical behaviour of a chicken egg

Abstract

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.
