摘要 这项研究探讨了利用水果在撞击过程中的加速度历史来预测水果损坏程度的可能性。对 240 个“金冠”苹果的冲击测试结果表明，当水果从不同高度掉落到不同的冲击表面（不同的缓冲）时，可以通过基于 a）仅从加速度和冲击质量数据导出的参数（R2=0.862）和 b）冲击加速度曲线的傅里叶变换系数（R2=0.883）的多元回归模型来预测碰伤体积。
ABSTRACT This study examined the possibility of using the acceleration history of a fruit during impact to predict the degree of fruit damage. Results of impact tests with 240 'Golden Delicious' apples indicate that when the fruits were dropped from different heights onto different impacting surfaces (cushioned differently), the bruise volume could be predicted by multiple regression models based on a) the parameters derived solely from the acceleration and impacting mass data (R2=0.862) and b) Fourier-transform coefficients of the impact acceleration curves (R2=0.883).
