    苹果-瓦楞纸板缓冲跌落动力学模型

    Cushioning dropping modeling of a falling apple on the corrugated board

    • 摘要: 基于瓦楞纸板受冲击压缩变形的特征,提出一表征其非线性冲击力-变形模型,结合其跌落冲击试验结果表征模型参数。在此基础上,建立“富士”苹果-瓦楞纸板缓冲跌落动力学模型方程,进行不同高度下的苹果缓冲跌落冲击响应的理论分析,并与试验结果进行比较。结果表明,试验结果与理论模型结果吻合性好,所提出苹果-瓦楞纸板缓冲跌落冲击模型能合理地表征苹果缓冲跌落冲击动力学特征,瓦楞纸板能显著降低苹果跌落的冲击加速度。研究结果为果品缓冲包装设计提供了理论基础。

       

      Abstract: The dynamic nonlinear force versus deformation model of the corrugated board was proposed, and its model parameters were estimated in terms of the dynamics characteristics obtained by dropping compression tests. The cushioning dropping model of the falling apple on the corrugated board was developed. The cushioning dropping tests were conducted on fresh ‘Fuji’ apples at four heights: 10, 20, 30, 50 cm. Then, the dropping impact responses of theoretic model and tests for apples were obtained. Results show that the cushioning dropping model was good agreed with test data, and the corrugated board notably reduced the impact accelerations of apples. The cushioning dropping model provides the foundation of cushioning packaging design for apple fruit.
