摘要
为了研究不同储藏温度下芒果的力学特性随储藏期的变化,本文对芒果的应力松弛、蠕变特性等力学指标进行了测试,并结合Maxwell模型模型对所得实验结果进行拟合。结果表明,在10℃、20℃、30℃的储藏温度下,芒果的坚实度、主松弛时间以及弹性模量均随着储藏天数的增加而呈现显著的下降趋势。针对芒果力学特性的研究结论将对芒果在仓储、运输环节中的精准管理提供一定的参考意义。
In order to study the mechanical propertites of mango under different storage temperatures,the mechanical index of mango were tested under the mode of stress relaxation and creep,which combined with Maxwell model to fit the experimental results.The results indicated that the firmess of mango,main relaxation and elastic modulus presented significent downtrend with the extending of storaging time under different storage temperatures such as 10℃,20 ℃ and30℃.These results can be expected for precise management of mango storage and transporation.
