摘要
运用有限元法分析了鸡蛋蛋壳的受载特性,并通过试验比较验证了模拟数值解的可行性.有限元分析获得:在相同外载加压下侧面受载的应力和变形都大于大端受载,越厚的蛋壳能承受的应力越大,蛋的形状系数对蛋的强度影响无明显相关性.为今后对鸡蛋受载特性的进一步研究提供了参考.
The research on the loading behaviour of fowl egg was carried out using finite element simulation. The reliability of simulation numerical solutions was verified through comparing the experimental outcome. The stress distribution and displacement of eggshell were analyzed under different conditions of force or pressure. The correlation between the loading properties and geometrical characteristics of the egg was investigated by using a numerical model analysis. The results showed that the strength and displacement of the lateral side of the egg was greater than the ogival nose. The stress increased as the egg＇s thickness increased, and there was no obvious correlation between the loading properties of eggshell and the ogival factor.
