摘要: |
根据苹果振动试验结果,得出了损伤与振动加速度、振动时间、承载重量之间的多元线性回归方程。通过对这些数学模型的分析,说明了几种常用损伤评价指标的合理性和可比性,为预测振动损伤提供了依据。在相关分析中提出了用粘弹特性评价机械损伤的新方法。 |

Abstract: |
Based on the results of apple vibrating test,a multi-linear regrssion equation was derived for the acceleration of damage and vibration,vibrating time and loading weight.The analytical results of these models indicated that the several usual indexes for evaluating apple damages were rational and comparable so as to provide the base for the estimation of vibrating damages caused to apples. Also,in the correlative analysis,a new method by using viscoelasticity to evaluate the mechanical damages to apples was advanced in this paper. |
