【摘要】：为提供一种更加符合蛋壳结构力学特性的测试蛋壳弹性模量的方法,以鹅蛋壳为研究对象,对鹅蛋进行轴向压缩试验,获取赤道部位的经向、纬向应变与轴向载荷之间的关系;依据旋转壳无矩理论推导出蛋壳弹性模量和泊松比的表达式,并根据试验数据求取试验鹅蛋壳的弹性模量和泊松比。测得试验鹅蛋壳弹性模量的平均值为47.33GPa,方差为5.68;泊松比平均值为0.411,方差为0.064。本研究所述测试方法更加符合蛋壳结构力学特性,可以为蛋类的生产、运输、加工装置设计提供参考。
[Abstract]:In order to provide a new method to measure the elastic modulus of egg shell, the axial compression test of goose egg shell was carried out to obtain the relationship between meridional, zonal strain and axial load. The expressions of elastic modulus and Poisson's ratio of egg shell are derived according to the theory of rotation shell without moment, and the elastic modulus and Poisson's ratio of the tested goose egg shell are obtained according to the experimental data. The average elastic modulus of eggshell was 47.33 GPA, the variance was 5.68, the average Poisson's ratio was 0.411, and the variance was 0.064. The testing method is more suitable for the mechanical properties of eggshell structure and can be used as a reference for the design of egg production, transportation and processing device.
